Server Error (500) on Django when template debug is set to False?
Question: I am seeing `Django 500 Error` when I set `DEBUG = False` in Django. I am
using `Django 1.5 and Python 2.7`. I have also included `ALLOWED_HOSTS` in my
template. Here's my full settings.py:

What's wrong?

Updated the logging as Ryu_hayabusa suggested and I am getting this error in
the console:

    
    
    Unhandled exception in thread started by <bound method Command.inner_run of <django.contrib.staticfiles.management.commands.runserver.Command object at 0x22e08d0>>

Answer: For django v 1.5+ , in your settings.py file, Make the configuration
ALLOWED_HOSTS = ['*'] if you want a quick fix

If you are really going production (and concerned about security), put allowed
host names in ALLOWED_HOSTS
