I migrated Mediawiki to following versions:
Skin Pivot: 2.3.0
It shows only the first Tab and the layout is screwed up. I checked the other posts in here but I think the problem is another one. Well, I am a newbie on SMW.
Error: Unknown module: jquery.ui.tabs
Uncaught ReferenceError: wgNamespaceNumber is not defined
Does anyone have a clue where the problem could be. My intention was first that the problem could be the skin but also other skins show the same result.
