我建议创建Custom User Role, 使用add_role() 功能，例如“站点管理员”或“子管理员”（或任何您想调用的功能）。那么，你可以assign specific user capabilities 从而为用户提供您想要的功能，而不是您不想要的功能。

例如：

<?php
add_role( 
    // Role slug
    \'sub-admin\', 
    // Role display name
    \'Sub-Admin\', 
    // Capabilities
    array(
        activate_plugins,
        add_users,
        create_users,
        delete_others_posts,
        delete_pages,
        delete_plugins,
        delete_posts,
        delete_private_pages,
        delete_private_posts,
        delete_published_pages,
        delete_published_posts,
        delete_users,
        edit_dashboard,
        edit_files,
        edit_others_posts,
        edit_pages,
        edit_posts,
        edit_private_pages,
        edit_private_posts,
        edit_published_pages,
        edit_published_posts,
        edit_theme_options,
        export,
        import,
        list_users,
        manage_categories,
        manage_links,
        manage_options,
        moderate_comments,
        publish_pages,
        publish_posts,
        read_private_pages,
        read_private_posts,
        read,
        remove_users,
        switch_themes,
        unfiltered_upload,
        upload_files
    ) 
);
?>

可用的插件有多个可用的插件，可提供用于创建和修改用户角色的UI，包括：

• Members Plugin
