Looks like we might have a problem with JetPack (sounds familiar???)
I click on "show stats" and I get this:
We're experiencing some problems on WordPress.com and we are in read-only mode at the moment. We're working hard on restoring full service as soon as possible, but you won't be able to create or make changes to your site currently.
Ahem... I guess the boys at JetPack have Q/A that leaves something to be desired of... Just sayin'
