Hello,
I’m hosting a WordPress site on a server managed via HestiaCP (installed through the web interface).
Until recently, it was possible to stay logged into the same WordPress user account from two devices (e.g. desktop and mobile) at the same time — for example, for responsive design testing.
However, now it seems that logging in on one device immediately logs the other out. No plugin has been added or changed, and session settings in PHP (php.ini) appear standard. PHP versions are 8.0 / 8.1 / 8.2 – the site uses 8.2.
I haven’t manually changed anything on the server. Could this be related to:
a recent update of HestiaCP?
new default PHP session behavior?
something introduced in WordPress or server-level configuration?
Has anyone experienced this behavior recently?
Thanks in advance for any help or insight!
