User Profiles Not Working in Production

I have an app that lets users have profiles. Everything works fine in
development, but its not working in production.

When you navigate to a user profile, an error occurs. For example
http://leximo.org/users/Druwerd

just brings up an error.

Here are the log files for development and production.

Development:

For some reason it gives me an ActionView:TemplateError in production
but not in development.

I could use some help.
