[SOLVED] Can't define default cache Django

I'm trying to setup caching in Django, but it won't let me define a default cache. I'm not overly concerned with what type of cache I use (I have tried Filesystem and Database Cache.)

But even when copy + pasting their example code the error checker tells me:

?: (caches.E001) You must define a 'default' cache in your CACHES setting.

I have also tried to put the CACHES setting at the bottom of the settings.py file to make sure anything the CACHES setting might depend on is initialized.

My code is as follows:

CACHES = {
   'default': {
      'BACKEND': 'django.core.cache.backends.filebased.FileBasedCache',
      'LOCATION': '/var/tmp/django_cache',
   }
}

The full error message is:
