Having trouble today staying logged in. Everytime I move to a new thread or try to post I'm logged out for some reason.
This was happening to me too. Started last night. Happening on Safari for MacOS and iOS. Didn't test other browsers. Seems to be working correctly now after being booted and re-logging in dozens of times.
Same here. Sent a message via Contact Us early this a.m. No response yet. If I can relog in and post it's only to have it kick me out again. After logging in a few times I end up with screen message "Your account has temporarily been locked due to failed login attempts". I waited a few hours to try again, now, and so far logged in, been kicked out, came here and trying to post this. Hope it's fixed soon, but you aren't the only one!
It didn't matter one way or the other. Too - for the last couple years, I've never specifically checked that feature and the site wouldn't behave like this; logging me out, every time I'd click on "New Posts", which seems like the same behavior OP experienced. I can't repro the behavior now w/or without checking the box, FWIW. So it seems to have resolved.
There was an update that might have been causing the issue. I rolled that back. Let me know if that seems to have fixed it.
