我也有同样的问题。我变了一点，我不再是一个编码员了。函数get\\u oembed\\u response\\u data中的php文件如下：

/**

 *
 * @since 4.4.0
 *
 * @param WP_Post|int $post  Post object or ID.
 * @param int         $width The requested width.
 * @return array|false Response data on success, false if post doesn\'t exist.
 */

    $post  = get_post( $post );
    $width = absint( $width );


    $title = $post->post_title;
    $title = str_replace("[:it]","",$title);
    $title = str_replace("[:en]","",$title);
    $title = str_replace("[:]","",$title);


    if ( ! $post ) {
        return false;
    }

    if ( \'publish\' !== get_post_status( $post ) ) {
        return false;
    }
