Refs 109. I fixed the previous error as well as a Cookie overflow error that popped up. Now when I click through, it just reroutes you back to the main page. I have also been running into problems with the callback - based on stackoverflow discussions, it looks like Twitter's system is not particularly supportive of running local servers as callbacks. I think the current situation has to do with the twitter method in users/omniauth_callbacks_controller.rb. It looks like it runs the authentication but doesn't log that as making a user. Stackoverflow suggests making some sort of flag so that the system knows that a user has been created. I also started tinkering with a dummy facebook account in relation to this, but then I decided to stick with the work on twitter.
