In Blog Comments Section Disappeared 10 days ago

Homestead my web platform for many years. On the Blog page always place for reader to make comments. 10 days ago that disappeared. Tech support says it has something to do with the way my site is linked to Facebook. Always until recently Facebook attacted to my site worked fine.

And the poof ...

I am not sure what I did to turn off the comments section ... and even less sure how to reconfigure the connection ...
