Autologin First Login Page option can be useful when you want to redirect your newly registered users to a specific page – in case they are first logging in to the site using autologin link.
If a user already logged in using the login form, Autologin First Login Page won’t work, as this option basically checks whether specific user logged in to the site at least once or no.
If there are no previous logins and user is trying to login for the first time using the autologin link, that specific user will be redirected to the page set in Autologin First Login Page option.
Autologin First Login Page option can be configured from Memberium => Settings => Login tab.
