Thread:Project:Support desk/PrefSwitch: Impossible to make running PrefSwitch on brand new mediawiki installation, both local or hosted

Product	Version MediaWiki	1.18.1 PHP	5.3.3 (cgi-fcgi) MySQL	5.0.51a-24+lenny5-log PrefSwitch (Version 0.1.2) $wgDefaultSkin = "vector";

Installation instruction followed: http://www.mediawiki.org/wiki/Extension:PrefSwitch http://www.mediawiki.org/wiki/Manual:Update.php

Problem: Although the extension is installed, and php restarted (locally with a terminal, and hosted via web process), the extension does not appear at all. Only the standard vector MediaWiki 1.18.1 edit tool is present when editing.

I'm blocked with this. I really do not know how to solve it. I've read dozens of pages about.

Thanks for your help
