But wait , as through the Cite extension appears to be installed , it isn't being 'used' by MediaWiki yet , thereby making it unused yet.(You can verify it here - http://www.betaarchive.com/wiki/index.php?title=Special%3AVersion).
Neither the Cite extension , nor the other bundled extensions like Nuke and ConfirmEdit(anti-spam tools) are being used by MediaWiki yet.
This seems to be because the 'require_once line' is not added to the LocalSettings.php for Cite and the other bundled extensions.
First , verify that the extension folders exist in the extensions directory in the wiki.
Then ,
(for Cite) add this line in LocalSettings.php
require_once "$IP/extensions/Cite/Cite.php";
Then , the extension should work.
Hope this helps.
