Just in case you run into this when running your development server. I ran the development server as root like this: sudo python manage.py runserver 0.0.0.0:80 in order to test the site with an iPad in the same LAN network. The cache files generated in that session belonged to root. So when I ran the project the next day NOT as root I got the permission denied error.
