Relevant backtrace:
{{{
File

packages/django/contrib/sites/models.py"
in _get_site_by_id
37. return SITE_CACHE[site_id]
File "/srv/www/teckids-website/venv/lib/python3.5/site-
packages/multisite/hacks.py" in
__getitem__
124. raise KeyError(key)
}}}
In theory, there cannot be a KeyError there, unless the cache is cleared
while the method is running. The code does not seem to be thread-safe.
