Вопрос генерации крошки

Question

Нужна помощь со списком Breadcrumb Ошибка, которая появляется из старого генератора Breadcrumb внутри темы.

На моем сайте WordPress я использую плагин Yoast для генерации Breadcrumbs. И созданные таким образом хлебные крошки имеют правильную структуру.

Но в теме есть старый код генерации Breadcrumb (присутствует в 2 php файлах). Это было с разметкой Data-Vocabulary.org вместо Schema.org, я фактически заменил устаревший Data-Vocabulary.org на Schema.org, но структура списка Breadcrumb на самом деле неверна.

см. Скриншот

Таким образом, чтобы полностью устранить ошибку, мне нужно полностью удалить генератор хлебных крошек из двух приведенных ниже PHP.

1. td_page_generator. php

<?php class td_page_generator {

//this is the global page wrap, it prepares the page for the pagebuilder
