Hi everyone!

I hope you could give me a hint, how to solve this problem.
The following content-type worked relly fine until now:
http://todesanzeigen-online.de/suche-traueranzeigen/traueranzeigen

What happened:

• I imported a lot of datasets of a given content-type. Everything seemed ok.
  I changed the template for another content-type (the one with the problem now)
  and the validation type: Seblod validation is off. I use another one (jQuery).
  
• Now everytime I save this content-type (not the one with the import) I get the error:
  "Invalid Parent ID" and the hint that there might be the same alias.

• I checked the Joomla _content table. The article is saved there with an unique alias.
• But the joined data in _cck_core and _cck_store_form_traueranzeigen is not created.

Two questions:

1. What could be the reason for that? 
2. How could I debug? When I switch on debug in seblod for "everyone" nothing is shown on the frontend.

Thanks a lot community :-) !!
