Extended Permissions error

I'm trying to get the user email from facebook link with the local account, so i've been reading some issues and found out that I need to enable the extended permissions module, and then select the email permissions on the extended permissions tab, the thing is that the checkboxes are not shown in the tab and i get the following error

FQL query failed. The query was "SELECT permission_name, header, summary FROM permissions_info WHERE 1".: REST API is deprecated for versions v2.1 and higher
