Getting the site content type coulmns failed

That is the message what I see when trying to publish my InfoPath Form to the server. Everything worked fine with an ordinary site, but at this time I tryed to publish it in PWA. I guess there is no difference between them, but the issue still confuses me.

The form library, which I created for this kind of templates has an "Allow management of content types?" option set to Yes.

Also I created a content type named Form and added a standard columns to it. But the problem still exists.

Any suggestions are kindly appreciated.

Sincerely yours, Andreas.
