Celery error, unregistered task
Received unregistered task of type u'<mytask>'.
The message has been ignored and discarded.
Did you remember to import the module containing this task?
Or maybe you are using relative imports?
Please see http://bit.ly/gLye1c for more information.
One possible solution:
Restart celery on the server.
This error can be due to celery not restarting after you’ve added a task.
