end

and what do you have in your routes.rb file? for example, i'd expect something like 'devise_for :users, :controllers => { :omniauth_callbacks => "users/omniauth_callbacks" }' — blotto
Neil he meant edit your post and paste it there with the code properly formatted there... not in the comments. — mystic cola

Misspelled something in my routes file. It should have said omniauth_callbacks

Fbapp::Application.routes.draw do
  devise_for :users, controllers: {omniauth_callbacks: 'users/omniauth_callbacks'}
  resources :posts

  get "pages/home"
  root "pages#home"
