One solution that seems to work is unchecking the 'stay signed in' box at login. No idea why this should be; a pity we have to work it out and spread the word and not the provider. In at least one case this solution also fixed an issue linked with followers.
Thanks, Porky. You mean I uncheck "stayed signed in," or the commenter?
Wow. My own comment disappeared until I signed out and back in.
I'm not sure to be honest as I've been lucky enough not to have the problem. I'd guess the commenter. I don't know why this kind of thing can't be fed to all bloggers via a message on the dashboard.
This looks like a good place to do the "testing 1-2-3" spiel.Heathansson
Mine began working again last night. I had tried the 'no checking the stay signed in box' as well. I've found that it works fine with it checked now, but I do have to enable outside cookies in order to post. So be it. At least I can post. Good luck fellows.
