Hi,
I am just seeing the same problem.
On the affected site I tried changing the page ID. It used to be just a number like
199246526755363 but now it has changed to Broodjesbar-Bocadillo-199246526755363.
Either of these do not result in showing the Facebook feed.
However when I try with just a single name like Webriti or Adidas it does show the feed. I hope this helps in troubleshooting the situation.
Kind regards,
Eelco
