How to display a Facebook Feed on my site with coding

Site URL: https://www.flemingtonpres.org/

I had coding on my site to display our Facebook feed that is no longer working. The Facebook header still appears, but the feed is blank with a loading icon. I tried updating the coding and switching from a Code block to an Embed block but neither worked. I also tried the Meta for Developers page plugin which didn't work.  Is there any current coding out there I can use? I was hoping not to have to create an account somewhere to get a widget.

It looks fine to me

This is happening to us as well. We can't find a resolution anywhere. Occasionally it seems to be fixed but then happens again. When it is happening and someone goes to the site it jumps them directly down to that FB error section too - which is exceptionally annoying.
