i am still getting logged out.
at first, i thought that perhaps my firefox ad blockers might be causing a problem but i am always logged into 8+ websites 24x7. some sites do auto-log out users after a period of inactivity.
so i disabled all blockers for your website and i still get auto-logged out.
then i tried microsoft edge, which has no blockers or addons, and i am still getting auto-logged out.
