Python Django: RuntimeError: Model class django.contrib.sites.models.Site (error goes on)

I'm currently writing a web-application with Python Django. My problem is, that i recently installed django-relationships, added it to my INSTALLED_APPS inside the settings.py.

Since then I'm getting this wired error and I have NO Idea what it means.

Somebody out there can help me?

add django.contrib.sites to your INSTALLED_APPS and SITE_ID = 1 in your settings.py that solved my problem

It seems django-relationships depends on the Site model. You must add django.contrib.sites to your INSTALLED_APPS as well.

The second error indicates that django-relationships tries to import create_many_related_manager from django.db.models.fields.related. This function was removed in Django 1.9. If a newer version is available, you can try if that works. If not, django-relationships is not usable with Django 1.9.
