I have AMPZ and TAGZ installed on two of my three sites. When I am attempt to share an article from one my sites, yet no image is shown. I cleared the cache for that site, to no avail. Ran the Facebook Debugger which comes back with two errors:

Provided og:image URL, images/courses/SWU730/Start_Lines_Webinar_Social_Image.jpg was not a valid URL.
The following required properties are missing: fb:app_id

I have tried to use the TAG info that is a part of the article as well, re-ran the debugger and received the same error.

Any tips on how I can fix this?

Thank you in advance.
