title: I keep getting "Not found. Authentication passthru" for Facebook connect login with Devise - Need debug advice
body: <p>I've seen a couple people ask a similar question, but I really need advice on how to debug this issue. I'm trying to setup facebook connect using Devise using the article here: <a href="https://github.com/plataformatec/devise/wiki/OmniAuth:-Overview" rel="nofollow">https://github.com/plataformatec/devise/wiki/OmniAuth:-Overview</a></p>
  
  <p>Every time I click on the login with facebook link, I get the blank page that just says: Not found. Authentication passthru. Clearly, there is no JavaScript/ajax setup on the prior page to pull up the facebook login screen.</p>
  
  <p>I know this can work on my system, as I made a blank project with the exact same code from the link above and it works. Of course, my project is much bigger with lots of code, so I'm trying to figure out what in my project is causing this not to fire.</p>
  
  <p>Any help on how to debug is appreciated.</p>
  
  <p>Thanks!</p>
