In an attempt to circumnavigate the above problem, I installed Facebook Open Graph protocol plugin v2.0.7.
Nothing changed — FB still worked fine with all older posts, but continued to generate “Title” and “Description” but no thumbnail image for both the “Everything Is Illuminated” post and ANY NEW POST.
——————————————
I even created this 200×200 pixel image, whose URL I included for the plug-in’s “Default Image URL to use” option.
FB never used that image… even when I checked the “Force Fallback Image as Default ” box.
——————————————
I went back to the FB debugging page, to see what was different now that I had installed the Facebook Open Graph protocol plugin.
Looking at the “Mystery Tree” page’s results, I see that the original four “Open Graph Warnings That Should Be Fixed” were no longer listed…
…however, in their place I see two NEW warnings:
Meta with name instead of property The meta tag on the page was specified with name ‘author’, which matches a configured property of this object type. It will be ignored unless specified with the meta property attribute instead of the meta name attribute.
og:image should be larger Provided og:image is not big enough. Please use an image that’s at least 200×200 px. Image ‘https://alanb.org/ImperfectFifths/__Images/Riverdale%20Tree%20with%20Straight-up%20Branches%20-%20Image%20132.jpg’ will be used instead.
That second one is bizarre, as the image in the post (which FB used to generate the thumbnail) is significantly larger than 200×200.

Looking now at the “Everything Is Illuminated” page’s results, I see that the original four “Open Graph Warnings That Should Be Fixed” were no longer listed…
… and that it only lists one of the two new warnings found in the “Mystery Tree” results:
Meta with name instead of property The meta tag on the page was specified with name ‘author’, which matches a configured property of this object type. It will be ignored unless specified with the meta property attribute instead of the meta name attribute.
There was no “og:image should be larger” warning.
Looking at the “Raw Open Graph Document Information,” I see the following lines:
Meta Tag <meta property=”og:image” content=”https://alanb.org/ImperfectFifths/__Images/SVA-illuminated-Pyrus-calleryana.jpg” />
Meta Tag <meta property=”og:image” content=”https://alanb.org/ImperfectFifths/__Images/APLogo-200×200.jpg” />
So FB sees two images (one is the 200×200 “Default Image URL to use” and the other is the main, much larger, image)… yet there is no image listed in the “Object Properties” section under “og:image”

What’s going on here?
Has anyone else started having similar problems?
What other information can I provide to better help you figure this out?
THANKS!!!!!!!!!!!!!!!!
