Up until two days ago, I was able to post Facebook Status through Notification Center without any issues. However, I am not getting error messages saying that "Connection to Facebook has failed" However, I can still share through Safari and other application without any issues. (including Preview, etc) I have tried all the possible solution that was mentioned when this issue previously arose when using within Safari. (which included erasing cookies and resetting Safari), and installing the latest Combo update (which, by now is 10.8.4). But none of the methods has worked so far. I have even tried re-setting the PRAM, and issue still persists. I am basically stumped. Is there any solution, or is this issue on Apple or Facebook's end? (I heard it's authentication, but I doubt it, since it still works on my iPad running iOS 6) I posted this in Apple Support Community, but I decided to post it here also, to see if anyone here knows how to fix the issue. Note that I have no issues when posting to Twitter. That still works.
