I also just tried posting from a different WordPress/domain after updating the Facebook app…and, I got the exact same error message. There are no warnings on my Facebook app page….everything seems to be ok there.
Very strange…..my personal Facebook credentials I manage about 10 Facebook pages…..So, in the social publisher area, there is the pull down for which page I want to publish to…..ONLY the page I really want to publish to I get the error message……I have no problems publishing to any of the other business pages. I also deleted all trash items.
I deleted the Facebook app and created a new one and got the same error message.
I have the same problem, and found the problem is the “OG tags” which are duplicated, if you post a new entry, and then try to post it on FB page/profile, you’ll get the error or non-data, until you use the Debug or a few minutes later…
I’m looking for solution this!
If you believe the issue is duplicate Open Graph protocol markup on the individual post try entering the URL of the individual post in the Facebook URL Debugger
