You never mentioned anything about Facebook or Events on your previous posts… “Events” is a custom post-type which is neither Post nor Page. I believe it is by BuddyPress, right?
Anyway, try to download and install the theme found on this page: https://ronangelo.com/frontier/
See if that fixes the issue.
Note: Please don’t create new topics every time you reply on the same issue. Just reply here on your first topic. This is the second type I’ve merged your reply.
