title: Cordova Facebook plugin - cannot show dialog
body: <p>I'm trying the basic example seen here : <a href="https://github.com/jeduan/cordova-plugin-facebook4#show-a-dialog" rel="nofollow">Facebook4 plugin</a></p>
  
  <pre><code>facebookConnectPlugin.showDialog({
      method: "send",
      caption: "Check this out.",
      link: "http://example.com",
      description: "The site I told you about",
      picture: "http://example.com/image.png"
  }, function(result) {
      // Success!
      $timeout(function () {
          $ionicLoading.hide();
      });
      console.log("success", result);
  }, function(err) {
      // An error occured. Show a message to the user
      $timeout(function () {
          $ionicLoading.hide();
      });
      console.log("error - ", err);
  });
  </code></pre>
  
  <p>And I get this error message : </p>
  
  <pre><code>Cannot show dialog
  </code></pre>
  
  <p>I'm really not sure what's going on... And looking for a long time now without making any progress. Any help ?</p>
  
  <p>I don't think it's linked but the permissions asked on login are</p>
  
  <pre><code>["public_profile", "email", "user_birthday"]
  </code></pre>
  
  <p>Thanks !</p>
