Somehow, it just does't work. Our staff has experienced this issue for a long time. User doesn't clear browser's cache at all, yet the logged in user(user/1) is still automatically logged out.
I did something very stupid. I was blocking older users that never logged I have blocked also the admin access, becuase I am getting the message that is not activated.
Can somebody help me, please. I am feeling a little nervous :-/
