Hi,
1) the box is unchecked, this feature was not used at all. It must be something else.
2) The link in my WP menu administration is same as the one in user’s profile, which I used till now. Even after adding it to WP menu it doesn’t work and the result is same. After clicking on it the page asks me whether I really want to log out. I click yes and after it I’m back on my website and still logged in. After it links “register” and “login” are redirected to page “Account”. I have to restart my computer to log out properly. I tried it in Chrome and Edge.
