[Django]-Django not displaying error traceback to browser – just 500 page

The following is required in settings module in order to display diagnostic page after errors:

• DEBUG is True
• The client (web browser) is connected from localhost or from any IP address listed in INTERNAL_IPS.
• The variable TEMPLATE_CONTEXT_PROCESSORS contains "django.core.context_processors.debug" or is left on the default value.

You can distinguish the web server’s error 500 page from Django’s error page easy by different text like this:
“… There’s been an error. It’s been reported…” (This is from the default template.)
if you do import handler500 from django.conf.urls (or django.conf.urls.defaults in old Django) in the main urlconf.

You could have an error in your middleware in process_request before you can get to the error page. Although, that you could access some pages would suggest that this is not the problem.

try this instead:

set DEBUG = True
TEMPLATE_DEBUG = DEBUG

comment DEBUG_PROPAGATE_EXCEPTIONS=True, this should work. Please try.
