Call to undefined method PhocacartRenderFront::getClass()

[Schuflebuur]

Error: Call to undefined method PhocacartRenderFront::getClass() after update to 3.3.0 and 3.3.1

I need some help on: When I join to an existing Kategorie then the system crashes with the above error.
A restore from a previous backup fixes the problem.
best regards
Felix

Hi, can you enable debug mode and post here the more detailed error message (including the file and line of the error).

Is your Phoca Cart Search module enabled? If yes, what happens when you disable it? (for test only)
