Python Django Latex Permissions Problem

It was a very unlikely problem. Apparently although apache was
configured, someone in the past had run some instances of manage.py
Maybe they were stuck or they were running in the background.

Once all python instances were killed and Apache was restarted,
everything worked as a breeze.

Thanks for the help though
