I see this has been raised several times before but I haven’t seen a resolution – if there is one, please point me to it.
I have been using the WordPress app on WinPhone 7 for several weeks with no problem. Today I’m getting “api_key does not belong to administrator of blog”. I’ve reinstalled the app, and also reinstalled JetPack. I have retrieved the api key and entered it into the app manually. Still no joy – I’m out of ideas now. Can you help?
