Facebook Debugger Error: "You must preload this data. TAAL[BLAME_file]"

When debugging a website with a Like button here:

https://developers.facebook.com/tools/debug/og/object?q=http%3A%2F%2Fwww.arcosjapan.com%2Fscroll%2Fcaresox-hc.html

It throws a critical error:

"You must preload this data. TAAL[BLAME_file]".

I have installed hundreds of like buttons and have never run across this. Does anybody know what it means? I am aware of the other is开发者_运维问答sue that it is pointing out on that page: "The app ID specified within the "fb:app_id" meta tag is not allowed on this domain." and I am pretty sure that is not the issue as my app is correctly configured.

Facebook Debugger is broken every once in a while. Now it seems to be working again. It gave the same error message just a couple of days ago.
