Ruby on rails devise facebook認証反応しない

##deviseでfacebookユーザー認証がうまく機能していない

導入したはじめは，facebookで登録するのボタンを押してみると、ちゃんとfacebookAPI側のページ切り変わって、ごの名前で続けますか？みたいなところまでは表示されました。

問題はそのあとなのですが、それ以降ボタンを押しても、なんの反応もしなくなりました。まして、databaseの中を確認してもユーザーが追加されているわけでもありませんでした。

gitのチュートリアルをみて進めました。

  # up on your models and hooks.

  # ==> Warden configuration
  # If you want to use other strategies, that are not supported by Devise, or

  # ==> Mountable engine configurations
  # When using Devise inside an engine, let's call it `MyEngine`, and this engine
  # is mountable, there are some extra configurations to be taken into account.
  # The following options are available, assuming the engine is mounted as:
  #
  #     mount MyEngine, at: '/my_engine'
  #
  # The router that invoked `devise_for`, in the example above, would be:
  # config.router_name = :my_engine
  #
  # When using OmniAuth, Devise cannot automatically set OmniAuth path,
  # so you need to do it manually. For the users scope, it would be:
  # config.omniauth_path_prefix = '/my_engine/users/auth'
