GoViral extension and FB_LOGIN_CANCELED

We’re using the milkmangames GoViral extension (3.0.3) for a current project and running into a weird error where logging in to the iPhone5 raises a¬†gvFacebookLoginCancelled (FB_LOGIN_CANCELED) event even though we click the [OK] button on the login dialog.

If this happens to you, check your Facebook app settings (at http://developers.facebook.com/) to make sure that your app ID matches the one used in your application descriptor.

We discovered the fix when trying the same app on iPad1.  It uses the external Facebook app for authentication Рand the app raised an error message with more details on it.
