Ruby on Rails Hash cannot be converted to string error

Question

Can anyone add meaning to this. I installed the restful_authentication plugin and when i tried to run the rails server, this poppedup. I get the same error having tried to manually remove the plugin and when i run all rails commands: rake, plugin install, plugin remove, etc.

Any ideas?
