It's been like this with me for about a week. I tried to clear the history, 3 browsers and nothing helped.
Same here, maybe even a bit longer than one week. I tried several browsers across several devices, no change.
But prior to this, just a few days before , I had a strange forum experience - got logged out on all devices for a day, even though I usually stay signed in permanently by default. When trying to sign in a message would pop up, stating that my password was incorrect. The next morning I was able to sign in on my phone, with the same old password, yet at the same time this password would get rejected if I tried to use it on my laptop.
Eventually I got logged out on my phone too. Again.
In the end I lost my patience and just changed the password on both devices. But shortly after the whole forum slowed down for me, and it's still dragging, it's just the amount that varies from time to time.
