Manual:Configuration settings (alphabetical)

This is an index of all supported configuration settings based on the DefaultSettings.php file.

Never edit DefaultSettings; copy appropriate lines to LocalSettings.php instead and amend them as appropriate.

This index is in alphabetical order (ignoring the $wg prefix). Note that the only setting without this prefix is $IP, which is listed under I.

 Note: Settings removed in versions of MediaWiki prior to 1.19 are no longer listed here. Please use the search box to find the relevant manual page (e.g. Manual:$wgAllowAnonymousMinor).
