[Typo3-dev] error with typo3.8 beta2 and templa voila 0.4.0 ?

[Jens]

Hello,

when I try to add new content in the FE edit mode. (Admin 
panel/editing/create new content element) I get the following error:
The requested URL /typo3conf/ext/templavoila/mod1/db_new_content_el.php 
was not found on this server.

Of course the file is on the server. I didnt have that problem with 3.7.
Is this just my problem ?

Greetings Jens.
