Description
I'm currently teaching myself Django.
So, I successfully installed
Operating System: Windows XP SP3
Python: Version 2.7
Django: Revision 13446
Database: PostgreSQL 8.4
Postgre Driver: psycopg2.2.2
LAMP: XAMPP (Apache Friends Edition)
Python Interface: mod_wsgi
I configured a virtual host for my Django project.
For the most part, everything is "playing well together".
However, when I try to use Django with the Apache server, I get an error which seems similar to "invalid" ticket #12730... except for I don't have deseb.
This is my errorlog:

I saw a suggestion (elsewhere on the web) that I might fix this if I downgrade psycopg2 to 2.0.14, but to even test this fix, I will also need to downgrade Python to 2.6 ... but so far as I can tell, the problem isn't with either of those since they are both working fine together with python manage.py runserver
Moreover, I have confirmed the problem isn't with my Apache configuration, since everything works fine if I replace Postgre with SQLite3
