I’ve run into the same problem with Site Stats and have been messing with it for the last two hours, with no results. I’m also getting the message: Your WordPress.com account, is not authorized to view the stats of this blog. It was working fine earlier today.
So, does anyone know who to contact to get the problem resolved.
(Yes, esmi, I read the thread you’re posting on all the threads, but it does not provide any information about getting this problem fixed and I currently have no interest in jetpack.)
