[Solved]-Django : Syncdb incorrectly warns that many-to-many field is stale

Pay attention to the message. It’s not claiming that your field is stale – it’s talking about an entry in the Content Types model.

In the shell, do this:

from django.contrib.contenttypes.models import ContentType
ct = ContentType.objects.get(app_label='Apps', model='app_users')
ct.delete()
