I have been trying to install ProjectHQ.
I have gotten to the point where I try to access the page with the web browser.
I only see the contents of the index.wsgi file.
I see that wsgi.conf and wsgi.load are in the mods-enabled directory.
I have rebooted (running Ubuntu Karmic, 64-bit)

Re: index.wsgi content is displayed instead of ProjectHQ
Did you add the WSGIScriptAlias in your web server configuration, as per Configuring Your Web Server?
