Facebook parsing broken

Yesterday posting links from my WP site worked as expected. Last night Godaddy was having issues going really slow… so slow I was getting timeout issues while working on stuff on the site. I suspect something got screwed up because of that.
Today links from my site only show generic info in facebook posts. The post thumbnails don’t show, the description doesn’t show. In an attempt to fix it… I updated my theme to it’s latest version, Avada 9.3…, The Yikes Mailchimp plugin was toasted by the same event – I removed it and reinstalled it… it is now working. I’m deeply frustrated.

I came across this Facebook link checker. It seems to suggest my site isn’t exposing the fetch info it’s supposed to.

I tried installing Yoast SEO to see if giving an alternate image and description at the page level via their tool would work. It made no difference. Facebooks link check still shows no data.

Here are a couple links that should have featured images and descriptions showing on Facebook.
(This first link worked fine yesterday.)

I would so appreciate any insights…
