добавление новой страницы в админку opencart

Я пытаюсь добавить новую страницу в раздел администратора в opencart, и мне удалось создать все необходимые файлы и разрешения для ее отображения, но она не отображает никаких результатов. Я пытаюсь создать страницу, на которой я могу добавлять / редактировать / удалять рецепты minecraft. Но вместо того, чтобы отображать результаты для каждого рецепта в базе данных, он просто показывает «Нет результатов!» Пожалуйста, помогите мне, я застрял.

Таблица базы данных:

На странице просмотра я распечатал $recipes, и он просто отображает array(), поэтому я предполагаю, что проблема где-то внутри контроллера, где $recipes вставляет в него свои данные. Но насколько я могу судить, похоже, что все настроено правильно! Я сбит с толку, лол.
