Si necesitas añadir capacidades al rol de Editor tales como administrar usuarios usa los siguientes snippets en el functions.php
Permitir al editor administrar usuarios:
/*
* Let Editors manage users, and run this only once.
*/
function isa_editor_manage_users() {
if ( get_option( 'isa_add_cap_editor_once' ) != 'done' ) {
// let editor manage users
$edit_editor = get_role('editor'); // Get the user role
$edit_editor->add_cap('edit_users');
$edit_editor->add_cap('list_users');
$edit_editor->add_cap('promote_users');
$edit_editor->add_cap('create_users');
$edit_editor->add_cap('add_users');
$edit_editor->add_cap('delete_users');
update_option( 'isa_add_cap_editor_once', 'done' );
}
}
add_action( 'init', 'isa_editor_manage_users' );
Evitar que el editor elimine el usuario administrador
//prevent editor from deleting, editing, or creating an administrator
// only needed if the editor was given right to edit users
class ISA_User_Caps {
// Add our filters
function ISA_User_Caps(){
add_filter( 'editable_roles', array(&$this, 'editable_roles'));
add_filter( 'map_meta_cap', array(&$this, 'map_meta_cap'),10,4);
}
// Remove 'Administrator' from the list of roles if the current user is not an admin
function editable_roles( $roles ){
if( isset( $roles['administrator'] ) && !current_user_can('administrator') ){
unset( $roles['administrator']);
}
return $roles;
}
// If someone is trying to edit or delete an
// admin and that user isn't an admin, don't allow it
function map_meta_cap( $caps, $cap, $user_id, $args ){
switch( $cap ){
case 'edit_user':
case 'remove_user':
case 'promote_user':
if( isset($args[0]) && $args[0] == $user_id )
break;
elseif( !isset($args[0]) )
$caps[] = 'do_not_allow';
$other = new WP_User( absint($args[0]) );
if( $other->has_cap( 'administrator' ) ){

Ocultar el administrador de la lista de usuarios
// Hide all administrators from user list.
add_action('pre_user_query','isa_pre_user_query');
