[TYPO3-templavoila] TemplaVoila Error with Multilanguage in T3 V6.0

[Philipp Zilliken]

I encountered the typo3 Mapping Error mentioned in the extension FAQ.
My default language subpages map corectly, but in my second page 
language, i can only see the mapping error.

Do you have any advice how i can solve this problem?
