Turns out that the problem with Pinning was due to a change with Pinterest. I still want to investigate and see when this happened, but here is what I got from Tech Suppport at my hosting site:
“What I found was Pinterest did not allow to save pins from an insecure source. SSL was installed for your domain but your website was not using the SSL. I forced your website to redirect to https which is now secured.
There were insecure links on your website, which I corrected to https. All your pages and links are now secured with SSL.”
And, it is working now.
