I am running EE 5.2.6 and I have repeated issues with getting logged out of the control panel when I am in the middle of working on an entry.
This issue happens so frequently I filed a Bug Report https://github.com/ExpressionEngine/ExpressionEngine/issues/286.
Derek said that the problem was not reproducible, yet I can reproduce it virtually every time I create an entry. I have set the site time zone in ExpressionEngine according to my local time zone. My computer is a Mac and the time is set automatically, so technically they should be in sync.
According to Derek, the control panel should not log out until after an hour of inactivity, yet I can be in the middle of a lengthy entry and suddenly without warning get logged out, losing all changes. I have turned revisions on, but they do not save regular enough to be of any use. I had three versions of today’s entry all from 4:06 pm. I was logged out at 5:00 pm losing all edits to the very lengthy entry.
I am happy to make any changes to my configuration - see image - if I can just get this problem solved. I would love to hear from anyone that has a functioning configuration.
