  <p>I used <code>python manage.py celeryd -B</code> to run celery beat.
  It seems that running the celery worker is not the issue, but the <code>celerybeat</code> worker is not initialising. any suggestions as to where i could find the database which celery is trying to access?</p>
  
  <p>I'm running django=1.5 and django-celery==3.1.10</p>
