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:

    /usr/lib/ruby/gems/1.8/gems/activerecord-2.2.2/lib/active_record/ attribute_methods.rb:255:in `method_missing'

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

I could use some help.
