[TYPO3-english] Cannot add content elements in page module

[Bernhard Schmid]

Hi list,

I just installed Typo3 4.4 and the latest TemplaVoila extension. 
Everything seems to work fine except adding content elements in the 
TV-page module. Everytime I click "Creat new element" in the page 
module, I don't get any elements I can choose from: "Please select which 
kind of page content you wish to create:" followed by blankness.

Any ideas what's wrong here?

Regards
Bernhard

P.s.: Adding content elements in list view DOES however work...
