Facebook has decided to retire certain public API endpoints without warning on April 4th, 2018. This is affecting parts of our plugin Feed Them Social. It will no longer be possible to display feeds from Groups or Events at this time with our plugin (vs 2.4.1+). Facebook has effectively cut off the group endpoints and it is required you get an app approved to display events. For these reasons we are going to retire the Events feed and Group feed until they are made public again.
We apologize for any inconvenience and also for not being able to give you any prior warning to this happening due to Facebook not giving us the opportunity. Please know we will be diligently working on improving Feed Them Social to adapt to these changes if and when they become available.
