The pattern is that the Vector/WikiEditor components work fine on pages that have been protected from local site customizations (e.g. Preferences, Login etc.). On others it is interrupted due to an uncaught exception being thrown from your custom site script.

When visiting your wiki, the first thing I see in this error in the Console: Uncaught ReferenceError: Geo is not defined

This error is also visible in your. Click on "Console" or click the red error icon in the bottom right corner, that brings you to the error message in the console. From there you can debug it.

It originates from. If you enable debug mode (http://www.mobadaten.info/wiki/MoBaDaten:Hauptseite?debug=true), then you can see that it comes from MediaWiki:Common.js.

It appears you pasted lots and lots of javascript from other wikis into MediaWiki:Common.js (without? knowing how it works) and in doing so you included several code paths that refer to variables that don't exist on your wiki. Please remove everything in MediaWiki:Common.js. That should make it work again. Once you verified that that is indeed what caused it, you can start adding back parts that you really need. If it goes wrong again, at least you know where to look :)
