Login / Logout legend

Hi,
How I can do so that when the user already logged into this site , the word "login " is not displayed , I would like to show " logout"

Thanks a lot

Hi,

It's a default WordPress menu (with the "login" menu item), so you can use i.e. the following plugin:
https://pl.wordpress.org/plugins/nav-menu-roles/
and assign the "login" menu item only for Logged Out Users, then create new menu item "logout" and assign it only to Logged In Users, don't forget to add "gk-login-popup" custom CSS class for both menu items.

Excelente!!!
