The people I work with have a "member" account.
Once identified, people can see the site without being able to administer it.
Until then it works.
But, the navigation menu is down 48px.
In fact, since the person is identified, this causes a reservation of the management menu although it does not appear for the member.
It's annoying because it changes the esthetics of the site.
Since the member does not have access to the admin, it would automatically hide the space usually used for the menu that manages the site.
An evolution would it be possible?
Session Invalidated. Session IP "2a01:cb18:3c3:4b00:9427:472c:d030:641e" did not match provided IP ".....................".
(I mask the ip)
<?php return [ 'security' => [ 'session' => [ 'invalidate_on_ip_mismatch' => false, ] ] ];
