When I press "Remember me?" when i log in, at least i stay logged in all the time.
So basically really all the time, which I'm positively surprised
[well, of course I go here all the time, that's also the reason]...
What is the session timeout in the forum ...? Admittedly, that’s exactly the Remember Me button that should override it. Unless there is a more common error on that button...
I also have the same on all devices, but I also always have the same browser and basic settings: Chrome
Could there be a problem with your browser, such as its cookies, settings, etc.?
[a single bug in the remember me button is probably unlikely]
