Hybridauth Elgg doesn't work with Facebook login ?

Hi to all!

I have two errors with facebook login using Hybridauth Plugin.

1. "Can't Load URL: The domain of this URL isn't included in the app's domains. To be able to load this URL, add all domains and subdomains of your app to the App Domains field in your app settings."

or this (depends of what url I fill in):

2. Given URL is not whitelisted in Client OAuth Settings: This redirect failed because the redirect URI is not whitelisted in the app’s Client OAuth Settings. Make sure Client and Web OAuth Login are on and add all your app domains as Valid OAuth Redirect URIs.

how can I fix it ? Twitter works fine, Facebook login no.

I have red a lot of forums, tried a lot of solutions and URL in the facebook developers page of App, but nothing works.

Do you know how to fix it ?

thank you all!


I have these info in Hybridauth settings:
