created a superuser using Django admin command. I have successfully logged
in but when I am trying to logout it throws an error

I have investigate few things and got that
{{{
env/lib/python3.8/site-packages/django/contrib/sessions/backends/db.py #
103
self.model.objects.get(session_key=session_key).delete()
}}}
unable to delete session object because its expecting integer but string
in being store in django_sesison.session_key
Please look into this.
Thanks!

It looks like an issue in `metatags` not Django itself.
