I forgot to stop the work on a sub-task for 18 days. Then I tryed to stop the work. But instead of stoping the work I got only the message Error 500. Then I`ve tryed to delete the sub-task and got the same Error message again. Also to create a nother new Time-record for this task got the same eroor. At least I was deleting the whole task including all sub-tasks and got no errors.
