title: Problems configuring an application in Facebook (website with Facebook login)
body: <p>all:</p>
  
  <p>We have a software developer building a web site with Facebook login for our company. They have told us to register a Facebook application.</p>
  
  <p>For the moment, the beta application is hosted in a development environment. I would like to start testing also the Facebook integration. But when I access to the application page in Facebook, I get an <a href="http://i.stack.imgur.com/NXOmd.png" rel="nofollow">error</a>.</p>
  
  <p>I think it might be related to an attribute I find in the first page of the app configuration. The attribute is called "<a href="http://i.stack.imgur.com/fcuQv.png" rel="nofollow">Hosting URL</a>".</p>
  
  <p>The option seems to be linked to some kind of hosting service provided by Heroku. I don't know exactly what is that, but I would say we do not need it. We will use our own hosting server and, what's more, our application is developed in a language different that the one Heroku supports.</p>
  
  <p>Could somebody confirm us which is the problem and, if it is possible, give us a hint to solve it? </p>
  
  <p>Thank a lot in advance,
  -The SportPoket team</p>
