facebook extended permissions
hi,
i added a btn "Attend" that should make the user attending an event on facebook
but i am receiving the error response
"message": "(#299) Requires extended permission: rsvp_event",
i added this permission to facebook_helper.js
var url = "https://www.facebook.com/dialog/oauth...=" + Facebook_Settings['client_id'] + "&redirect_uri=" + callbackUrl + "&scope=user_events,publish_actions,user_groups,rsvp_event&response_type=token";
but with no luck , did i miss anything ?
thanks
