Hi Ashfame,
Thanks for all your input. Your help is really appreciated. I’m also having a similar problem with my blog. I just installed your plugin, and I hope the problem is alleviated in the next 24 hours.
Out of curiosity, how can I fix the problem on my own? When I use Facebook’s lint tool, I get a message about a Bad Image URL and other missing properties (https://developers.facebook.com/tools/lint/?url=http%3A%2F%2Fblog.melschwartz.com%2F).
Your feedback is most welcome. Thanks!
