Problem
The system shows a message that the class was changed by another user while you had the edit window open.
Possible cause
Another user saved changes to the same class while you were editing it. To avoid overwriting those changes, the system refuses to save.
Solution
Reload the page to see the latest information.
Make your changes again in the updated class.
Click Save.
