Utilizó un gancho para ocultar algunos elementos 

use WHMCS \ View \ Menu \ Item como MenuItem;

add_hook ('ClientAreaSecondarySidebar', 1, function (MenuItem $ secundariaSidebar)
{
    $ secondarySidebar-> getChild ('Soporte')
        -> removeChild ('Descargas');
});

add_hook ('ClientAreaSecondarySidebar', 1, function (MenuItem $ secundariaSidebar)
{
    $ secundariaSidebar-> getChild ('Support')
        -> removeChild ('Network Status');
});

add_hook ('ClientAreaSecondarySidebar', 1, function (MenuItem $ secundariaSidebar)
{
    $ secundariaSidebar-> getChild ('Support')
        -> removeChild ('Announcements');
});

add_hook ('ClientAreaPrimaryNavbar', 1, function (MenuItem $ primaryNavbar)
{
    $ primaryNavbar-> removeChild ('Estado de la red');
});

 

cuando estoy en la pagina de area de clientes funciona todo pero al ir a otra pagina genera el erro 

 

¡Ups!

[brian!]

you need to check that the element exists before trying to remove it...
