Password not recognized?

[MikeG]

As of this AM, the site keeps logging me out and then doesn't recognize my password when I try to log back in. I can only get in by resetting my password (to the same one as before). But that doesn't last long, whereupon the site logs me out again and the cycle starts over again. I haven't changed any browser security settings or anything, so I don't think the problem is on my end.
