FaceBook error displays can be as mysterious as Blogger error displays. But, there is hope - provided by FaceBook Developers.
The FaceBook Developers Debugger tool can be invaluable, in diagnosing a problem with our blogs, and FaceBook Open Graph code.
Diagnose FaceBook problems, before asking for assistance.
When we try to share a blog post with FaceBook, and get a mangled mass of pictures and / or text, it's a good idea to diagnose the problem, before requesting help. Sometimes, the Debugger will provide the right clues, and help us identify our problems, immediately.
Provide the URL of the blog, and hit "Debug".
To use the tool, just provide the URL of the blog, or the post, which has a problem.
Paste a URL into the box, and hit "Debug".
Use "Show existing scrape information" or "Fetch new scrape information".
Start with the immediate errors.
Check the raw Open Graph tags. And the "Open Graph properties", that were the usable part of the code that you provided.
The complete code listing is in "Scraped URL".
View an image of what your share will look like, when it hits the Wall. And click on "Scraped URL", for the complete code listing.
You'll have a choice to "Show existing scrape information" or "Fetch new scrape information" - which can be useful, if you are diagnosing a problem after you shared your blog post. For help on using the tool, you'll see the hint.
See our Webmasters doc for more info on the Facebook crawler and debugging your Open Graph markup.
Run the Debugger - then post in the FaceBook Community, if you wish.
And, if worse comes to worst, and armed with Debugger logs as examples of the problem, we can report the problem to FaceBook Support. Having a copy of the "Scraped URL" page will be useful then.
