[Facebook] Are you getting one of those errors?
(#283) Requires extended permission: manage_pages
(#200) Requires extended permission
(#200) The user hasn’t authorized the application to perform this action
Facebook moves EVERYBODY to the API 2.3 on April 30, 2015. If you got one of those errors you were on API 1.0. SNAP Plugin is compatible with API 2.3 ONLY starting from version 3.4.16.
Please update your plugin to the latest version and re-authorize Facebook.
PLEASE DO NOT OPEN TICKETS ABOUT THAT. Latest version + re-authorization fixes that issue.
