URLs and file paths

These various web and file path variables are set to their defaults in Setup.php if they are not explicitly set from LocalSettings.php.

These will relatively rarely need to be set manually, unless you are splitting style sheets or images outside the main document root.

In this section, a "path" is usually a host-relative URL, i.e. a URL without the host part, that starts with a slash. In most cases a full URL is also acceptable. A "directory" is a local file path.

In both paths and directories, trailing slashes should not be included.

Detailed Description

Default values for MediaWiki configuration settings.

NEVER EDIT THIS FILE

To customize your installation, edit "LocalSettings.php". If you make changes here, they will be lost on next upgrade of MediaWiki!

In this file, variables whose default values depend on other variables are set to false. The actual default value of these variables will only be set in Setup.php, taking into account any custom settings performed in LocalSettings.php.

Documentation is in the source and on: https://www.mediawiki.org/wiki/Manual:Configuration_settings

Variable Documentation

$wgActionPaths = []

To set 'pretty' URL paths for actions other than plain page views, add to this array.

Example:
Set pretty URL for the edit action:
1 'edit' => "$wgScriptPath/edit/$1"

There must be an appropriate script or rewrite rule in place to handle these URLs.

$wgAdaptiveMessageCache = false

Instead of caching everything, only cache those messages which have been customised in the site content language.

This means that MediaWiki:Foo/ja is ignored if MediaWiki:Foo doesn't exist. This option is probably only useful for translatewiki.net.

Referenced by GetSlaveServer\execute(), and DatabaseMysqlBase\open().

$wgAllowCopyUploads = false

Allow for upload to be copied from an URL.

The timeout for copy uploads is set by $wgCopyUploadTimeout. You have to assign the user right 'upload_by_url' to a user group, to use this.

Definition at line 713 of file DefaultSettings.php.

$wgAllowJavaUploads = false

Allow Java archive uploads.

This is not recommended for public wikis since a maliciously-constructed applet running on the same domain as the wiki can steal the user's cookies.

$wgAllowSiteCSSOnRestrictedPages = false

Whether to allow site-wide CSS (MediaWiki:Common.css and friends) on restricted pages like Special:UserLogin or Special:Preferences where JavaScript is disabled for security reasons.

As it is possible to execute JavaScript through CSS, setting this to true opens up a potential security hole. Some sites may "skin" their wiki by using site-wide CSS, causing restricted pages to look unstyled and different from the rest of the site.

$wgAllowTitlesInSVG = false

Disallow <title> element in SVG files.

MediaWiki will reject HTMLesque tags in uploaded files due to idiotic browsers which can not perform basic stuff like MIME detection and which are vulnerable to further idiots uploading crap files as images.

When this directive is on, "<title>" will be allowed in files with an "image/svg+xml" MIME type. You should leave this disabled if your web server is misconfigured and doesn't send appropriate MIME types for SVG images.

$wgAntivirus = null

Internal name of virus scanner.

This serves as a key to the $wgAntivirusSetup array. Set this to NULL to disable virus scanning. If not null, every file uploaded will be scanned for viruses.

Definition at line 1223 of file DefaultSettings.php.

Referenced by UploadBase\detectVirus().

$wgAntivirusRequired = true

Determines if a failed virus scan (AV_SCAN_FAILED) will cause the file to be rejected.

Definition at line 1277 of file DefaultSettings.php.

Referenced by UploadBase\detectVirus().

$wgAntivirusSetup
Initial value:
= [
# setup for clamav
'clamav' => [
'command' => 'clamscan --no-summary '

Configuration for different virus scanners.

This an associative array of associative arrays. It contains one setup array per known scanner type. The entry is selected by $wgAntivirus, i.e. valid values for $wgAntivirus are the keys defined in this array.

The configuration array for each scanner contains the following keys: "command", "codemap", "messagepattern":

"command" is the full command to call the virus scanner - f will be replaced with the name of the file to scan. If not present, the filename will be appended to the command. Note that this must be overwritten if the scanner is not in the system path; in that case, please set $wgAntivirusSetup[$wgAntivirus]['command'] to the desired command with full path.

"codemap" is a mapping of exit code to return codes of the detectVirus function in SpecialUpload.

  • An exit code mapped to AV_SCAN_FAILED causes the function to consider the scan to be failed. This will pass the file if $wgAntivirusRequired is not set.
  • An exit code mapped to AV_SCAN_ABORTED causes the function to consider the file to have an unsupported format, which is probably immune to viruses. This causes the file to pass.
  • An exit code mapped to AV_NO_VIRUS will cause the file to pass, meaning no virus was found.
  • All other codes (like AV_VIRUS_FOUND) will cause the function to report a virus.
  • You may use "*" as a key in the array to catch all exit codes not mapped otherwise.

"messagepattern" is a perl regular expression to extract the meaningful part of the scanners output. The relevant part should be matched as group one (\1). If not defined or the pattern does not match, the full message is shown to the user.

Referenced by UploadBase\detectVirus().

$wgApiFrameOptions = 'DENY'

Disallow framing of API pages directly, by setting the X-Frame-Options header.

Since the API returns CSRF tokens, allowing the results to be framed can compromise your user's account security. Options are:

  • 'DENY': Do not allow framing. This is recommended for most wikis.
  • 'SAMEORIGIN': Allow framing by pages on the same domain.
  • false: Allow all framing. Note: $wgBreakFrames will override this for human formatted API output.

This path should contain $1, which is replaced by the article title.

Defaults to "{$wgScript}/$1" or "{$wgScript}?title=$1", depending on $wgUsePathInfo.

Definition at line 255 of file DefaultSettings.php.

$wgCapitalLinkOverrides = []
Since
1.16 - This can now be set per-namespace. Some special namespaces (such as Special, see MWNamespace::$alwaysCapitalizedNamespaces for the full list) must be true by default (and setting them has no effect), due to various things that require them to be so. Also, since Talk namespaces need to directly mirror their associated content namespaces, the values for those are ignored in favor of the subject namespace's setting. Setting for NS_MEDIA is taken automatically from NS_FILE.
Example:
1 $wgCapitalLinkOverrides[ NS_FILE ] = false;

$wgCdnReboundPurgeDelay = 0

If set, any SquidPurge call on a URL or URLs will send a second purge no less than this many seconds later via the job queue.

This requires delayed job support. This should be safely higher than the 'max lag' value in $wgLBFactoryConf, so that slave lag does not cause page to be stuck in stales states in CDN.

This also fixes race conditions in two-tiered CDN setups (e.g. cdn2 => cdn1 => MediaWiki). If a purge for a URL reaches cdn2 before cdn1 and a request reaches cdn2 for that URL, it will populate the response from the stale cdn1 value. When cdn1 gets the purge, cdn2 will still be stale. If the rebound purge delay is safely higher than the time to relay a purge to all nodes, then the rebound puge will clear cdn2 after cdn1 was cleared.

Set true to enable Oracle DCRP (supported from 11gR1 onward)

To use this feature set to true and use a datasource defined as POOLED (i.e. in tnsnames definition set server=pooled in connect_data block).

Starting from 11gR1 you can use DCRP (Database Resident Connection Pool) that maintains established sessions and reuses them on new connections.

Not completely tested, but it should fall back on normal connection in case the pool is full or the datasource is not configured as pooled. And the other way around; using oci_pconnect on a non pooled datasource should produce a normal connection.

When it comes to frequent shortlived DB connections like with MW Oracle tends to s***. The problem is the driver connects to the database reasonably fast, but establishing a session takes time and resources. MW does not rely on session state (as it does not use features such as package variables) so establishing a valid session is in this case an unwanted overhead that just slows things down.

  • type: DB type
  • load: Ratio of DB_SLAVE load, must be >=0, the sum of all loads must be >0. If this is zero for any given server, no normal query traffic will be sent to it. It will be excluded from lag checks in maintenance scripts. The only way it can receive traffic is if groupLoads is used.
  • groupLoads: array of load ratios, the key is the query group name. A query may belong to several groups, the most specific group defined here is used.
  • flags: bit field
    • DBO_DEFAULT – turns on DBO_TRX only if !$wgCommandLineMode (recommended)
    • DBO_DEBUG – equivalent of $wgDebugDumpSql
    • DBO_TRX – wrap entire request in a transaction
    • DBO_NOBUFFER – turn off buffering (not useful in LocalSettings.php)

    • DBO_SSL – uses SSL/TLS encryption in database connections, if available
    • DBO_COMPRESS – uses internal compression in database connections, if available
  • max lag: (optional) Maximum replication lag before a slave will taken out of rotation

These and any other user-defined properties will be assigned to the mLBInfo member variable of the Database object.

Leave at false to use the single-server variables above. If you set this variable, the single-server variables will generally be ignored (except perhaps in some command-line scripts).

The first server listed in this array (with key 0) will be the master. The rest of the servers will be slaves. To prevent writes to your slaves due to accidental misconfiguration or MediaWiki bugs, set read_only=1 on all your slaves in my.cnf. You can set read_only mode at runtime using:

1 SET @@read_only=1;

Since the effect of writing to a slave is so damaging and difficult to clean up, we at Wikimedia set read_only=1 in my.cnf on all our DB servers, even our masters, and then set read_only=0 on masters at runtime.

File backend structure configuration.

This is an array of file backend configuration arrays. Each backend configuration has the following parameters:

  • 'name' : A unique name for the backend
  • 'class' : The file backend class to use
  • 'wikiId' : A unique string that identifies the wiki (container prefix)
  • 'lockManager' : The name of a lock manager (see $wgLockManagers)

See FileBackend::__construct() for more details. Additional parameters are specific to the file backend class used. These settings should be global to all wikis when possible.

There are two particularly important aspects about each backend:

  • a) Whether it is fully qualified or wiki-relative. By default, the paths of files are relative to the current wiki, which works via prefixing them with the current wiki ID when accessed. Setting 'wikiId' forces the backend to be fully qualified by prefixing all paths with the specified value instead. This can be useful if multiple wikis need to share the same data. Note that 'name' is not part of any prefix and thus should not be relied upon for namespacing.
  • b) Whether it is only defined for some wikis or is defined on all wikis in the wiki farm. Defining a backend globally is useful if multiple wikis need to share the same data. One should be aware of these aspects when configuring a backend for use with any basic feature or plugin. For example, suppose an extension stores data for different wikis in different directories and sometimes needs to access data from a foreign wiki's directory in order to render a page on given wiki. The extension would need a fully qualified backend that is defined on all wikis in the wiki farm.

$wgFooterIcons
Initial value:

"copyright" => [
"copyright" => []

Abstract list of footer icons for skins in place of old copyrightico and poweredbyico code You can add new icons to the built in copyright or poweredby, or you can create a new block.

Though note that you may need to add some custom css to get good styling of new blocks in monobook. vector and modern should work without any special css.

$wgFooterIcons itself is a key/value array. The key is the name of a block that the icons will be wrapped in. The final id varies by skin; Monobook and Vector will turn poweredby into f-poweredbyico while Modern turns it into mw_poweredby. The value is either key/value array of icons or a string. In the key/value array the key may or may not be used by the skin but it can be used to find the icon and unset it or change the icon if needed. This is useful for disabling icons that are set by extensions. The value should be either a string or an array. If it is a string it will be output directly as html, however some skins may choose to ignore it. An array is the preferred format for the icon, the following keys are used:

  • src: An absolute url to the image to use for the icon, this is recommended but not required, however some skins will ignore icons without an image
  • srcset: optional additional-resolution images; see HTML5 specs
  • url: The url to use in the a element around the text or icon, if not set an a element will not be outputted
  • alt: This is the text form of the icon, it will be displayed without an image in skins like Modern or if src is not set, and will otherwise be used as the alt="" for the image. This key is required.
  • width and height: If the icon specified by src is not of the standard size you can specify the size of image to use with these keys. Otherwise they will default to the standard 88x31.

$wgForceUIMsgAsContentMsg = []

When translating messages with wfMessage(), it is not always clear what should be considered UI messages and what should be content messages.

For example, for the English Wikipedia, there should be only one 'mainpage', so when getting the link for 'mainpage', we should treat it as site content and call ->inContentLanguage()->text(), but for rendering the text of the link, we call ->text(). The code behaves this way by default. However, sites like the Wikimedia Commons do offer different versions of 'mainpage' and the like for different languages. This array provides a way to override the default behavior.

Example:
To allow language-specific main page and community portal:
1 $wgForceUIMsgAsContentMsg = array( 'mainpage', 'portal-url' );

Set this to false if you do not want MediaWiki to divide your images directory into many subdirectories, for improved performance.

It's almost always good to leave this enabled. In previous versions of MediaWiki, some users set this to false to allow images to be added to the wiki by simply copying them into $wgUploadDirectory and then running maintenance/rebuildImages.php to register them in the database.

$wgHTCPRouting = []

Routing configuration for HTCP multicast purging.

Add elements here to enable HTCP and determine which purges are sent where. If set to an empty array, HTCP is disabled.

Each key in this array is a regular expression to match against the purged URL, or an empty string to match all URLs. The purged URL is matched against the regexes in the order specified, and the first rule whose regex matches is used, all remaining rules will thus be ignored.

Example configuration to send purges for upload.wikimedia.org to one
multicast group and all other purges to another:
1 $wgHTCPRouting = array(
2  '|^https?://upload\\.wikimedia\\.org|' => array(
3  'host' => '239.128.0.113',
4  'port' => 4827,
5  ),
6  '' => array(
7  'host' => '239.128.0.112',
8  'port' => 4827,
9  ),
10 );

You can also pass an array of hosts to send purges too. This is useful when you have several multicast groups or unicast address that should receive a given purge. Multiple hosts support was introduced in MediaWiki 1.22.

Example of sending purges to multiple hosts:
1 $wgHTCPRouting = array(
2  '' => array(
3  // Purges to text caches using multicast
4  array( 'host' => '239.128.0.114', 'port' => '4827' ),
5  // Purges to a hardcoded list of caches
6  array( 'host' => '10.88.66.1', 'port' => '4827' ),
7  array( 'host' => '10.88.66.2', 'port' => '4827' ),
8  array( 'host' => '10.88.66.3', 'port' => '4827' ),
9  ),
10 );

$wgLegalTitleChars = " %!\"$&'()*,\\-.\\/0-9:;=?@A-Z\\\\^_`a-z~\\x80-\\xFF+"

Allowed title characters – regex character class Don't change this unless you know what you're doing.

Problematic punctuation:

  • []{}|# Are needed for link syntax, never enable these
  • <> Causes problems with HTML escaping, don't use
  • % Enabled by default, minor problems with path to query rewrite rules, see below
  • + Enabled by default, but doesn't work with path to query rewrite rules, corrupted by apache
  • ? Enabled by default, but doesn't work with path to PATH_INFO rewrites

All three of these punctuation problems can be avoided by using an alias, instead of a rewrite rule of either variety.

The problem with % is that when using a path to query rewrite rule, URLs are double-unescaped: once by Apache's path conversion code, and again by PHP. So %253F, for example, becomes "?". Our code does not double-escape to compensate for this, indeed double escaping would break if the double-escaped title was passed in the query string rather than the path. This is a minor security issue because articles can be created such that they are hard to view or edit.

In some rare cases you may wish to remove + for compatibility with old links.

Theoretically 0x80-0x9F of ISO 8859-1 should be disallowed, but this breaks interlanguage links

$wgLocalFileRepo = false

File repository structures.

$wgLocalFileRepo is a single repository structure, and $wgForeignFileRepos is an array of such structures. Each repository structure is an associative array of properties configuring the repository.

Properties required for all repos:

  • class The class name for the repository. May come from the core or an extension. The core repository classes are FileRepo, LocalRepo, ForeignDBRepo. FSRepo is also supported for backwards compatibility.
  • name A unique name for the repository (but $wgLocalFileRepo should be 'local'). The name should consist of alpha-numeric characters.
  • backend A file backend name (see $wgFileBackends).

For most core repos:

  • zones Associative array of zone names that each map to an array with: container : backend container name the zone is in directory : root path within container for the zone url : base URL to the root of the zone urlsByExt : map of file extension types to base URLs (useful for using a different cache for videos) Zones default to using "<repo name>-<zone name>" as the container name and default to using the container root as the zone's root directory. Nesting of zone locations within other zones should be avoided.
  • url Public zone URL. The 'zones' settings take precedence.
  • hashLevels The number of directory levels for hash-based division of files
  • thumbScriptUrl The URL for thumb.php (optional, not recommended)
  • transformVia404 Whether to skip media file transformation on parse and rely on a 404 handler instead.
  • initialCapital Equivalent to $wgCapitalLinks (or $wgCapitalLinkOverrides[NS_FILE], determines whether filenames implicitly start with a capital letter. The current implementation may give incorrect description page links when the local $wgCapitalLinks and initialCapital are mismatched.
  • pathDisclosureProtection May be 'paranoid' to remove all parameters from error messages, 'none' to leave the paths in unchanged, or 'simple' to replace paths with placeholders. Default for LocalRepo is 'simple'.
  • fileMode This allows wikis to set the file mode when uploading/moving files. Default is 0644.
  • directory The local filesystem directory where public files are stored. Not used for some remote repos.
  • thumbDir The base thumbnail directory. Defaults to "<directory>/thumb".
  • thumbUrl The base thumbnail URL. Defaults to "<url>/thumb".
  • isPrivate Set this if measures should always be taken to keep the files private. One should not trust this to assure that the files are not web readable; the server configuration should be done manually depending on the backend.

These settings describe a foreign MediaWiki installation. They are optional, and will be ignored for local repositories:

  • descBaseUrl URL of image description pages, e.g. https://en.wikipedia.org/wiki/File:
  • scriptDirUrl URL of the MediaWiki installation, equivalent to $wgScriptPath, e.g. https://en.wikipedia.org/w
  • scriptExtension Script extension of the MediaWiki installation, equivalent to $wgScriptExtension, e.g. ".php5". Defaults to ".php".
  • articleUrl Equivalent to $wgArticlePath, e.g. https://en.wikipedia.org/wiki/$1
  • fetchDescription Fetch the text of the remote file description page. Equivalent to $wgFetchCommonsDescriptions.
  • abbrvThreshold File names over this size will use the short form of thumbnail names. Short thumbnail names only have the width, parameters, and the extension.

ForeignDBRepo:

'class' => 'LocalisationCache'

Localisation cache configuration.

Associative array with keys: class: The class to use. May be overridden by extensions.

store: The location to store cache data. May be 'files', 'array', 'db' or 'detect'. If set to "files", data will be in CDB files. If set to "db", data will be stored to the database. If set to "detect", files will be used if $wgCacheDirectory is set, otherwise the database will be used. "array" is an experimental option that uses PHP files that store static arrays.

$wgLocaltimezone = null

Fake out the timezone that the server thinks it's in.

This will be used for date display and not for what's stored in the DB. Leave to null to retain your server's OS-based timezone value.

This variable is currently used only for signature formatting and for local time/date parser variables ({{LOCALTIME}} etc.)

Timezones can be translated by editing MediaWiki messages of type timezone-nameinlowercase like timezone-utc.

The maximum number of pixels a source image can have if it is to be scaled down by a scaler that requires the full source image to be decompressed and stored in decompressed form, before the thumbnail is generated.

This provides a limit on memory usage for the decompression side of the image scaler. The limit is used when scaling PNGs with any of the built-in image scalers, such as ImageMagick or GD. It is ignored for JPEGs with ImageMagick, and when using the VipsScaler extension.

Changes to LESS variables do not trigger cache invalidation.

If the LESS variables need to be dynamic, you can use the ResourceLoaderGetLessVars hook (since 1.25).

Maximum time in seconds to cache resources served by ResourceLoader.

Used to set last modified headers (max-age/s-maxage).

Following options to distinguish:

  • versioned: Used for modules with a version, because changing version numbers causes cache misses. This normally has a long expiry time.
  • unversioned: Used for modules without a version to propagate changes quickly to clients. Also used for modules with errors to recover quickly. This normally has a short expiry time.

Expiry time for the options to distinguish:

$wgResourceLoaderMaxQueryLength = false

If set to a positive number, ResourceLoader will not generate URLs whose query string is more than this many characters long, and will instead use multiple requests with shorter query strings.

This degrades performance, but may be needed if your web server has a low (less than, say 1024) query string length limit or a low value for suhosin.get.max_value_length that you can't increase.

$wgResourceLoaderValidateStaticJS = false

If set to true, statically-sourced (file-backed) JavaScript resources will be parsed for validity before being bundled up into ResourceLoader modules.

This can be helpful for development by providing better error messages in default (non-debug) mode, but JavaScript parsing is slow and memory hungry and may fail on large pre-bundled frameworks.

$wgResourceModuleSkinStyles = []

Skin-specific styles for resource modules.

These are later added to the 'skinStyles' list of the existing module. The 'styles' list can not be modified or disabled.

For example, here is a module "bar" and how skin Foo would provide additional styles for it.

Example:
1 $wgResourceModules['bar'] = array(
2  'scripts' => 'resources/bar/bar.js',
3  'styles' => 'resources/bar/main.css',
4 );
5 
6 $wgResourceModuleSkinStyles['foo'] = array(
7  'bar' => 'skins/Foo/bar.css',
8 );

This is mostly equivalent to:

Equivalent:
1 $wgResourceModules['bar'] = array(
2  'scripts' => 'resources/bar/bar.js',
3  'styles' => 'resources/bar/main.css',
4  'skinStyles' => array(
5  'foo' => skins/Foo/bar.css',
6  ),
7 );

If the module already defines its own entry in skinStyles for a given skin, then $wgResourceModuleSkinStyles is ignored.

If a module defines a `skinStyles['default']the skin may want to extend that instead of replacing them. This can be done using the+` prefix.

Example:
1 $wgResourceModules['bar'] = array(
2  'scripts' => 'resources/bar/bar.js',
3  'styles' => 'resources/bar/basic.css',
4  'skinStyles' => array(
5  'default' => 'resources/bar/additional.css',
6  ),
7 );
8 // Note the '+' character:
9 $wgResourceModuleSkinStyles['foo'] = array(
10  '+bar' => 'skins/Foo/bar.css',
11 );

This is mostly equivalent to:

Equivalent:
1 $wgResourceModules['bar'] = array(
2  'scripts' => 'resources/bar/bar.js',
3  'styles' => 'resources/bar/basic.css',
4  'skinStyles' => array(
5  'default' => 'resources/bar/additional.css',
6  'foo' => array(
7  'resources/bar/additional.css',
8  'skins/Foo/bar.css',
9  ),
10  ),
11 );

In other words, as a module author, use the styles list for stylesheets that may not be disabled by a skin. To provide default styles that may be extended or replaced, use `skinStyles['default']`.

As with $wgResourceModules, paths default to being relative to the MediaWiki root. You should always provide a localBasePath and remoteBasePath (or remoteExtPath/remoteSkinPath).

Example:
1 $wgResourceModuleSkinStyles['foo'] = array(
2  'bar' => 'bar.css',
3  'quux' => 'quux.css',
4  'remoteSkinPath' => 'Foo',
5  'localBasePath' => __DIR__,
6 );

$wgResponsiveImages = true

Generate and use thumbnails suitable for screens with 1.5 and 2.0 pixel densities.

This means a 320x240 use of an image on the wiki will also generate 480x360 and 640x480 thumbnails, output via the srcset attribute.

On older browsers, a JavaScript polyfill switches the appropriate images in after loading the original low-resolution versions depending on the reported window.devicePixelRatio. The polyfill can be found in the jquery.hidpi module.

$wgSend404Code = true

Some web hosts attempt to rewrite all responses with a 404 (not found) status code, mangling or hiding MediaWiki's output.

$wgSharedDB = null

Shared database for multiple wikis.

Commonly used for storing a user table for single sign-on. The server for this database must be the same as for the main database.

For backwards compatibility the shared prefix is set to the same as the local prefix, and the user table is listed in the default list of shared tables. The user_properties table is also added so that users will continue to have their preferences shared (preferences were stored in the user table prior to 1.16)

$wgSharedTables may be customized with a list of tables to share in the shared database. However it is advised to limit what tables you do share as many of MediaWiki's tables may have side effects if you try to share them.

$wgSharedPrefix is the table prefix for the shared database. It defaults to $wgDBprefix.

$wgSharedSchema is the table schema for the shared database. It defaults to $wgDBmwschema.

Deprecated:

$wgThumbnailMinimumBucketDistance = 50

$wgThumbnailMinimumBucketDistance = 50;

If we want to render a thumbnail of width 220px, the 512px bucket will be used, because 220 + 50 = 270 and the closest bucket bigger than 270px is 512.

Definition: hooks.txt:189

Whether to support URLs like index.php/Page_title These often break when PHP is set up in CGI mode.

PATH_INFO may be correct if cgi.fix_pathinfo is set, but then again it may not; lighttpd converts incoming path data to lowercase on systems with case-insensitive filesystems, and there have been reports of problems on Apache as well.

To be safe we'll continue to keep it off by default.

Override this to false if $_SERVER['PATH_INFO'] contains unexpectedly incorrect garbage, or to true if it is really correct.

The default $wgArticlePath will be set based on this value at runtime, but if you have customized it, having this incorrectly set to true can cause redirect loops when "pretty URLs" are used.

$wgUseSharedUploads = false

If you operate multiple wikis, you can define a shared upload path here.

Uploads to this wiki will NOT be put there - they will be put into $wgUploadDirectory. If $wgUseSharedUploads is set, the wiki will look in the shared repository if no file of the given name is found in the local repository (for [[File:..]], [[Media:..]] links). Thumbnails will also be looked for and generated in this directory.

Advanced WAN object cache configuration.

Each WAN cache wraps a registered object cache (for the local cluster) and it must also be configured to point to a PubSub instance. Subscribers must be configured to relay purges to the actual cache servers.

The format is an associative array where the key is a cache identifier, and the value is an associative array of parameters. The "cacheId" parameter is a cache identifier from $wgObjectCaches. The "channels" parameter is a map of actions ('purge') to PubSub channels defined in $wgEventRelayerConfig. The "loggroup" parameter controls where log events are sent.
