I also found an error message in the apache logs:

I have also found an entry about this, unfortunately this does not help me.

Does anyone have an idea what it could be? Is more information needed?
Best thanks in advance!
Many greetings


this can be caused by the business processes module. You have version 2.3.0 installed, the current version is 2.3.1 which includes a minor fix for this error.

Either you deactive the module or you update to the current version:

Best regards
