Both are updated. "An unknown error has occured, please try back later" For weeks now. (Mavericks) iPhoto 9.5.1 I reinstalled facebook also. I'm at a loss now.
Operating system 10.9.1
iPhoto -> Preferences -> Accounts -> Delete your Facebook account and re-enter it.
Thank you, I tried it 3 times. It did not solve my problem.
