Log in Problems

I know I am probably in the wrong forum, but I can't get myself into "Glitches". For the past couple of days, I'm continually being asked to "log in" when I NEVER log out. Today, after I logged in, when I clicked on a Forum when I got there I was asked to Log In again; I'm going around in circles.

I don't know how I got on this time (luck or this particular forum?) nor if I can get back on after I get back from work, so I thought I'd better post SOMEWHERE with my problem.
I can still read posts (not logged in), but don't know how easy it will be for me to reply, if I can at all.

I feel like this has happened to me before, but I can't research this until tonight.

If a moderator can move this to where it belongs, I would appreciate it.

I'm not doing anything different than I've done before; nothing has been changed.

(I'm going to try not to change forums, at least now, since I don't know if I can get into some of the others. I'm going to just "minimize" the screen until I go to bed tonight.)
