title: Login through twitter failiing as "unauthorized" in OSQA
body: <p>I have installed OSQA on a site hosted on hostgator. The login functionality is working for google, yahoo and facebook, but when I click on twitter's icon it's generating an exception. I have already added the twitter consumer key and the twitter consumer secret through the admin interface. The exception I am getting is:</p>
  
  <pre><code>HTTPError at /account/twitter/signin/
  
  HTTP Error 401: Unauthorized
