I migrated Mediawiki to following versions:
MW: 1.35.2
SMW: 3.2.3
PageForms: 5.2.1
Skin Pivot: 2.3.0
PHP: 7.4.21
HeaderTabs: 1.3
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.
I get 2 errors in the javascript console:
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.
