Ok thx, but meanwhile i noticed 2 more little problems:
1. Quotes in title an descreption result in " " For Example: Hilfs Bremse = Hilfs "Bremse"
2. Moderating does not work. For my usergroup (administrator) is everything allowed in the galley usergroup options (esp. deleting comments done by other user/own comments). Because of the 404 error i did a lot of test comments. I cant delete them by avtivate the check box > moderate > delete entry.
I get an rihts problem error in this case. Edit > delete comment works without any problems.
