I had an interesting problem where I just couldn’t log into one of the blogs I manage today. I asked WordPress to send me a new password, tried it, but it wasn’t having any of it; I *still* couldn’t log in. I thought it was taking some time, so watched some satellite-to-Web video while I was waiting, but 30 minutes later it still hadn’t arrived.
It turned out that I must have had a rogue cookie that was causing a problem to WordPress. I deleted all my cookies and voila, I could log in once again.
Good to know huh?
