The DebugMode extension puts the wiki into debug mode, which means all MediaWiki debugging parameters are switched on.


  • Download and place the file(s) in a directory called DebugMode in your extensions/ folder.
  • Add the following code at the bottom of your LocalSettings.php :
    require_once "$IP/extensions/DebugMode/DebugMode.php";
  • Yes Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.

Configuration parameters[edit]

Level of debugging. Can be set to true to enable all debugging or false to do nothing.
Setting to false does not turn debugging off! It just leaves the existing settings alone.
Can be set using named constants in the DebugMode class, using bitwise operators:
Default value is a reasonable level of debugging, which is DebugMode::DEBUG_MODE_ALL minus DebugMode::DEBUG_MODE_VERBOSE.
Example: DebugMode::DEBUG_MODE_ALL ^ DebugMode::DEBUG_MODE_INI ^ DebugMode::DEBUG_MODE_PHP for “all but no PHP settings”.
An array of variables that should be ignored by the extension. Can be used for more fine-tuning of variables than allowed by $wgDebugMode. These vars can be any named variables known to the extension, including MediaWiki globals and PHP settings. Default is an empty array, nothing is ignored.
Example: array( 'wgDebugAPI' ) to ignore setting of $wgDebugAPI .
