title: Facebook Unity plugin: Given URL is not allowed by the Application configuration:
body: <p>I'm facing a strange Facebook plugin behaviour. </p>
  
  <p>Everything was fine until friday (07/08/2015). I was posting statuses without any problem, but now after I'm entering a login and a password of a test user account (App Settings -> Roles -> Test Users) Facebook showing me an error:</p>
  
  <blockquote>
    <p>Given URL is not allowed by the Application configuration: One or more of the given URLs is not allowed by the App's settings. To use this URL you must add a valid native platform in your App's settings.</p>
  </blockquote>
  
  <p>ATM I'm testing my app for the iOS platform and I can't add it, cause I don't have an app store ID yet.</p>
  
  <p>So what am I supposed to do to test my app's facebook functionality before posting it to the app store?</p>
