Setting DEBUG = False causes 500 Error

Question

Once I change the DEBUG = False, my site will generate 500 (using wsgi & manage.py runserver), and there is no error info in Apache error log and it will run normally when I change debug to True .

I'm using Django 1.5 & Python 2.7.3 here is Apache access log and without any log in apache error log

Django 1.5 introduced the allowed hosts setting that is required for security reasons. A settings file created with Django 1.5 has this new section which you need to add:

# Hosts/domain names that are valid for this site; required if DEBUG is False # See https://docs.djangoproject.com/en/1.9/ref/settings/#allowed-hosts ALLOWED_HOSTS = [] 

Add your host here like ['www.beta800.net'] or ['*'] for a quick test, but don't use ['*'] for production.
