Answer 1

Согласно моим знаниям, существует проблема с инструментом компиляции magento. Перед установкой любого расширения необходимо отключить процесс компиляции. Поэтому сначала удалите расширение. Затем пройдите ниже шагов.

1. Войти в magento admin и перейти «Система-> Инструмент-> Компиляция» И отключить компиляцию.
2. Теперь очистите кеш и снова установите расширение.
3. Выход из панели администратора.
4. Теперь ваше расширение должно работать. После этого вы можете снова включить процесс компиляции.
