category not created
1. Creating categories doesn't work properly. Seems a very random behaviour.
As administrator we couldn't create 1 category. Creating 2 categories worked OK.
After that we could create 1 category at the time.
Creating 1 category as a teacher : same problem.
As a student same problem. Even worse. Only 1 of two categories created.
2. Even when a category is created a message 'CategoryNotCreated' is always shown.
