I am getting this error after some time starting the server, what might be the reason? using code from github

Traceback (most recent call last):

I see this error too on an uncustomised AskBot install. It happens for various actions in the admin system, including logging out.

I am also encountering this issue after turning DEBUG to False.

I had similar problem(i use askbot as a part of another django app). Most probably you've missed to add skin directory to your staticdirs path.

  STATICFILES_DIRS += (

        ('default/media', os.path.join(ASKBOT_ROOT, 'media')),
    )

I have been encountering this same error here and there. Changing DEBUG to True revealed that this error is really hiding other errors. Once I fixed the error behind it, this stopped happening.

I was also getting `UndefinedError: 'skin' is undefined` when trying to save users in the Django admin (I'm trying to grant superuser permissions to some users). When I set `DEBUG = True` in `settings.py` this revealed that the underlying error was: IntegrityError at /admin/auth/user/23/ (1451, 'Cannot delete or update a parent row: a foreign key constraint fails (`askbot`.`askbot_groupmembership`, CONSTRAINT `authusergroups_ptr_id_refs_id_e728db87` FOREIGN KEY (`authusergroups_ptr_id`) REFERENCES `auth_user_groups` (`id`))') Googling for this error led me to http://askbot.org/en/question/3192/database-migration-failure/?answer=4104#post-id-4104, which recommends switching to Postgres or switching from MySQL InnoDB to MySQL MyISAM (which isn't that attractive because MyISAM doesn't support foreign keys).
