Since a few days I cannot create new issues in my project (no user). It always comes the error message that a category would have to be selected. This was not the case until now and we have no categories defined in the project.
Now I have tried in vain to introduce categories, but in the selection field of the issue still no category can be selected.
What is the reason that this field suddenly becomes a mandatory field and can I reset this?
Thank you very much
