Run 'tail -f' on the Apache error log when you make the request and see if anything at all is added. Tail both the main Apache error log and the virtual host specific one if you are using one. Ensure that:
LogLevel info is set at global Apache scope and not just in the virtual host. If 'info' you should see mod_wsgi log stuff when it loads the script file and restart processes, so there can't be nothing in the logs if you already have that set. In main Apache error log, especially keep an eye out for 'Segmentation fault' messages. You can ignore what IE shows you as it will put up its own crappy error pages and will hide the original server error page if it isn't over a certain length. Start also trying to add some print debug statements in your myapp.wsgi script file to see if it is actually being loaded and how far it is getting. See guidelines in: http://code.google.com/p/modwsgi/wiki/DebuggingTechniques#Apache_Error_Log_Files Also set DEBUG=True in Django settings file in case the problem is internal to how you have setup Django. You may have missing 404/500 error page handlers. Finally, you can always try and capture what is going in and out of WSGI application. See: http://code.google.com/p/modwsgi/wiki/DebuggingTechniques#Tracking_Request_and_Response In short, just start debugging it with low level techniques for working out how far it gets.
