MediaWiki Extensions How-To

Since the creators of the MediaWiki did such a poor job documenting this themselves, here goes:

1) An extension I tried to install does not seem to work.

To see if your extension was installed, Open the Special Pages section, then Version page. If it is not listed there, your extension was not installed.

You have to include a require_once(... call in your LocalSettings.php file. That call MUST BE AFTER THE

require_once( "$IP/includes/DefaultSettings.php" );

OR ELSE EXTENSION NOT ONLY WILL NOT WORK, BUT MAY BRING DOWN YOUR WIKI.

2) My site was brought down with an error message.

Your extension include call MUST BE AFTER THE

require_once( "$IP/includes/DefaultSettings.php" );

OR ELSE EXTENSION WILL BRING DOWN YOUR WIKI.

3) My extension still gives an error or does not work.

Go talk to the developer of the extension or MediaWiki. Not that they even have a real forum, however.
