WordPress SEO by Yoast: Hide Meta boxes in posts for non-admins

I was wondering how to remove Meta-boxes from the post page. I would like that only administrators or editors could see these. I saw similar topics on the forum, but none of them appears to be working. Any suggestions?

See WordPress SEO by Yoast: Hide Meta boxes in posts for non-admins

add_action('add_meta_boxes', 'yoast_is_toast', 99);
function yoast_is_toast(){
    //capability of 'manage_plugins' equals admin, therefore if NOT administrator
    //hide the meta box from all other roles on the following 'post_type' 
    //such as post, page, custom_post_type, etc
    if (!current_user_can('activate_plugins')) {
        remove_meta_box('wpseo_meta', 'post_type', 'normal');
    }
}
