Hi Thomas,
When I typed the following into my python console as advised:
>>> from django.contrib.session.backends import db
I got the following error:
Traceback (most recent call last): File "<stdin>", line 1, in <module> File
"/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/django/contrib/sessions/backends/db.py",
line 2, in <module> from django.contrib.sessions.models import

ENVIRONMENT_VARIABLE)ImportError: Settings cannot be imported, because
environment variable DJANGO_SETTINGS_MODULE is undefined.
I searched "/Users/myname/mysite3/settings.py" for the variable SESSION_ENGINE
but it is not defined in that file. I don't know where settings.SESSION_ENGINE
is defined???

Hi Simon,
your first traceback looked like this:
[Wed Aug 19 11:00:26 2009] [error] [client 127.0.0.1] mod_wsgi
(pid=120): Exception occurred processing WSGI script '/Users/myname/
mysite3/apache/myapp.wsgi'.

process_request
[Wed Aug 19 11:00:26 2009] [error] [client 127.0.0.1] ImportError: No
module named db
My line 9 of middleware.py of sessions looks like this:
engine = __import__(settings.SESSION_ENGINE, {}, {}, [''])
What does your variable settings.SESSION_ENGINE look like?
Is it 'django.contrib.sessions.backends.db'?
Try to import this as www user:
w...@host> python
>>> from django.contrib.session.backends import db
Does this work?
