Hello Adrian, Thank you for your reply. I checked my Apache error log but I could not see the traceback that could help. It ended up with
[notice] mod_python: (Re)importing module 'django.core.handlers.modpython' For this particular error of yesterday I found out that the reason, for HTTP 500 - Internal server error , was a missing "django.middleware.sessions.SessionMiddleware" in MIDDLEWARE_CLASSES But I receive 500 - Internal server error from time to time and then it takes some time( sometime long time) to find the reason. Would it be possible to add to Django some more debugging features? Or maybe there are and only I do not know how to use all available. Then it would be great if you could write some doc about? Thank you for your time and help. Best regards, lad.
