undefined method error for a polymorphic route

Hi, I'm trying to upgrade a 2.0.2 app to 2.2.2, but first I decided to
upgrade to 2.1.2 after reading some posts recommending to do this.

After firing up the app and running my tests, I now see that my
polymorphic routes seem to be broken.

NoMethodError: undefined method `footerpage_url' for #<PagesController:

k/lib/action_controller/polymorphic_routes.rb:105:in `send!'

Has anyone run into anything like this?
