Проблема при активации темы Opencart на ocStore

ArkNorm · November 27, 2022

После установки шаблона темы, пропала возможность входа в пункт "модификаторы" админки. Получается так: в админке нажимаю на пункт "модификаторы" и происходит переход браузере по адресу : http://1.japan-moto.com/admin/index.php?route=marketplace/modification&user_token=SgruObVrYOjftK19X9iSvXs4VBaH*** с ошибкой HTTP ERROR 500

На стандартной теме ошибки нет. Причина в новом шаблоне темы, которая написана под OpenCart (ошибки нет), а на ocStore (у меня) ошибка есть. Техподдержка темы обеспечивает поддержку установленную на движок с чистым кодом.

Техподдержка хостинга даёт такую ошибку:
PHP Fatal error: Cannot redeclare ControllerMarketplaceModification::edit() in /home/japanmot/1.japan-moto.com/system/storage/modification/admin/controller/marketplace/modification.php on line 1488

Я нашел строку 1488, и сверху ей подобную. Содержание кода в них разное. Удалил строку и содержание сверху. Ничего не изменилось. Потом восстановил и
удалил строку и содержание внизу, которое было в ошибке, строку 1488 и код внутри. Также ничего не изменилось. То есть нельзя зайти в пункт "модификаторы".
После каждого удаления чистил кеш через админку.

Прошу помощи, чтобы разобраться, где этот дублирующийся контент удалять.
