Unable to post to facebook and twitter
I've updated to OS X 10.8.2 on 19th. I've logged into facebook via "System Preferences". My address book has also started synchronizing with my facebook account. I've even shared a few pages from Safari with the share button. And I've also update my Facebook status from the "Click to Post" button in the notificaton center. But from this morning I'm unable to post to facebook and twitter. The "Post to facebook" and "click to tweet" buttons are not working. Moreover the safari share button works fine with twitter and nothing happens when I try to share on Facebook. I cannot understand why things turned this way now. The last app I've installed is "OnyX for Mountain Lion".
One more thing! If I restore my Mac using the recovery tool, will the data in other Hard disk partiotions remain safe? Or is the data in all the partiotions deleted?
MacBook Pro, OS X Mountain Lion (10.8.2)
