Content types disappear In some lists my content types all disappear. This especially affects Apache Solr for me. But also Views and Rules dont show the content types in some lists.

Interesting is that:


One content type is shown("Rezept") which is created by a custom module
All content types are shown correctly the moment i clear the cache.

The problem was caused by Domain Access Module. Since i didnt needed it anymore, i deactivated it.
