Django 1.7 upgrade error: AppRegistryNotReady: Apps aren't loaded yet

Question

I am trying to upgrade a project from Django 1.6 to 1.7. I get the following error:

[Thu Oct 09 14:16:41 2014] [error] [client 95.79.172.156] mod_wsgi (pid=1         


        

Answer 1

In my case, I forgot to add one of my sub-applications inside INSTALLED_APPS.

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'basketball',
    'basketball.area',
    'basketball.game',
    'basketball.player',
]
