python - Site matching query does not exist

Question

Python noob, as in this is my first project, so excuse my unfamiliarity.

The site was working very well until I clicked "log out" on my app. After that, the website would give me this error: DoesNotExist at /login/ Site matching query does not exist.

I searched everywhere and the only solution I get relates to setting up the site framework, SITE_ID, etc. I think those items on my computer are fine, but I can't find a walkthrough/guide to help me check on them.

Can anyone tell me what the problem is and how to fix it? Thanks in advance :3

 DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3', # Add 'postgresql_psycopg2', 'postgresql', 'mysql', 'sqlite3' or 'oracle'.
        'NAME': '/home/dotcloud/nhs.db',                      # Or path to database file if using sqlite3.
        'USER': '',                      # Not used with sqlite3.
        'PASSWORD': '',                  # Not used with sqlite3.
        'HOST': '',                      # Set to empty string for localhost. Not used with sqlite3.
        'PORT': '',                      # Set to empty string for default. Not used with sqlite3.
    }
}

If you don't have a site defined in your database and django wants to reference it, you will need to create one.

From a python manage.py shell :

from django.contrib.sites.models import Site
new_site = Site.objects.create(domain='foo.com', name='foo.com')
print (new_site.id)

Now set that site ID in your settings.py to SITE_ID
