Bug: Publicize to Facebook Not Working?

I have not changed anything (other than making a new post) on my blog or facebook page in months, but just recently, the post to Facebook option isn’t working. This happened for 2 websites, actually.

The China post was manually posted by me, but it did go to Twitter automatically.

“A Change Undisclosed” also had to be manually posted on Facebook.
