Manual:Configuration settings (alphabetical)

This is an index of all supported configuration options 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.
