I'm using AskBot 0.10.0 with LDAP authentication.
When signing in normally (by clicking Hi there! Please sign in), it works well.

However, when trying to post while not signed in, by clicking Login/Signup to post, I get:

Internal server error
system error log is recorded, error will be fixed as soon as possible
please report the error to the site administrators

As far as I can see, server logs do not show any error.

Have you tried enabling the debug mode with "DEBUG=True" in the settings.py?

With "DEBUG=True" I get the following error:

Facing the same issue here.
The problem is that behavior of flushing request session was changed in Django 1.8:

Changed in Django 1.8: Deletion of the session cookie is a behavior new in Django 1.8. Previously, the behavior was to regenerate the session key value that was sent back to the user in the cookie.

Hence no session_key is provided when creating an AnonymousAnswer object..
I'm totally new to askbot (started to play with it yesterday), so not really sure what a good solution would be in that case ?
