Фатальная ошибка Opencart с автоматическим заголовком SEO

Я установил верхний модуль, следуя инструкциям производителя, модуль устанавливается успешно, но затем я получаю фатальную ошибку, говорящую.

Неустранимая ошибка: вызов неопределенного метода ControllerModuleAutoSeoTitle :: render () в /home/clockworksignage/public_html/admin/controller/module/autoseotitle.php в строке 166

Пожалуйста, смотрите код ниже для autoseo title.php

Это строка 166
