I just noticed this started happening to me too. Just in the last few days. Each time I think it's because the moderators/ administrators have changed my name (upon my request
) but that's not the case (yet).
I don't know if this will help, but it won't hurt (except having to re-enter information on other sites): you could try deleting all history and cookies on your browser. Also updating your browser, or switching to another (Firefox or Chrome recommended), may be worth a try. I haven't tried these things as it's not too bad for me at the moment.
