“Save settings” on “Get Facebook Reviews” page

Hello,
After I’ve set the “Facebook App ID”, I click on the “Save settings” button, a pop-up appears in which is written :

Cette page ne fonctionne pas
Impossible de traiter cette demande via https://www.facebook.com à l’heure actuelle.
HTTP ERROR 500

The URL is :
