[Django]-Table django site doesn't exist

Probably something with migration order. You can try to remove django.contrib.sites from the INSTALLED_APPS and then syncdb. If that succeeds add django.contrib.sites and migrate again.

Alternatively you can add 'sites': 'my_app.sites_migrations to MIGRATION_MODULES and then make migrations for this with python manage.py makemigrations sites. Then running syncdb might work as well.
