[Mediawiki-l] Even if default skin is well set, still old skin

[Eric]

Hello, i'd like to use my own skin as defalut skin nammed vbwikiskin.

In localsetting.php :

I have : $wgDefaultSkin = 'vbwikiskin';

In my file VbWikiSkin.php :

I have : $this->skinname = 'vbwikiskin';

But still the old skin you can see here :

An idee ? Thanks
