This is an issue with the Facebook Widget, I think. When I edited the Meta description in Page Properties, it reverted to the previous meta description. That is, the previous wording showed up in the Facebook post that pulls in the meta description.
I've tried redoing the Facebook widget, redoing the page properties, deleting the browser cache, re-uploading the entire site (not just the parts that were changed), and am out of ideas of how to fix. Thanks for your help.
FB pulls this info from its own cache. It takes time for theser changes to register on FB. i would suggest you start by signing out of your FB account, flushing all cookies and local storage and signing in again. that way you force FB to re-scan every page you visit.
Thanks Mylenium. I'll try that. Makes perfect sense.
