我会这样做-只需添加一个新的mu插件或普通插件：

<?php
defined( \'ABSPATH\' ) OR exit;
/** Plugin Name: Limit Bulk actions to Editor & Admin */

add_action( \'wp_loaded\', \'wpse_53371_remove_bulk_actions\' );
function wpse_53371_remove_bulk_actions()
{
    if ( ! is_admin() )
        return;

    if ( ! current_user_can( \'delete_others_pages\' ) )
    {
        add_filter( \'bulk_actions-edit-post\', \'__return_empty_array\' );
        add_filter( \'bulk_actions-upload\',    \'__return_empty_array\' );
    }
}
