[Fixed]-Django – Configure multidomain with django.sites

Create a settings file for each domain where you list the apps that should be loaded and set SITE_ID to a different number for each file (if you are using the sites framework). Then create a wsgi.py file for each domain where you set the environment variable to the corresponding settings file as DJANGO_SETTINGS_MODULE.

You have to configure your web server to load the correct wsgi file for your domain.
