If the post limit isn’t high enough then there may not be any relevant posts to display.
If you don’t see any posts then your Access Token isn’t valid.
Solution: You don’t actually need your own Access Token in order to use the plugin, so try unchecking the Use my own Access Token setting and just using the token that’s built into the plugin.
Profiles have ‘Friends’, pages have ‘Likes’ and groups have ‘Members’.
If you have ‘Friends’ then it’s not a page or a group, it’s a personal profile.
If your page has any restrictions on it (age or location) then it means that users are forced to sign into Facebook in order to view your page.
This isn’t desirable for most pages as it means that it isn’t accessible by people who don’t have a Facebook account and that your page can’t be crawled and indexed by search engines.
Notifications such as ‘__ changed the cover photo’ or ‘__ created a group’ are filtered out and aren’t displayed.
Solution: Try creating a new post on your page or in your group and then viewing the plugin’s feed again.
The maximum post limit varies depending on how much data is associated with your posts, but it’s usually around 100.
The feed you’re trying to display has to be a publicly accessible page or an open group.
In order to retrieve your posts from Facebook the plugin requires a few basic PHP modules which are enabled on the majority of web servers by default.
