I have a similar problem. I can login to WP using my client’s login details but he cannot. It takes him back to the log in screen (he did get as far as the control panel once). I’ve tried setting him up again as a new user and again, I can login as him, but he can’t.
I’m on Windows XP with Firefox. He’s on Vista with Firefox and he’s using a plugin to manage passwords – but he’s been using that for a long time without issue
Any ideas?
