OpenCart — файл не найден (ошибка 404) на страницах категорий

У меня Opencart версии 1.5.6.4_rc, чистая установка.

Я создал несколько категорий продуктов (с SEO-дружественными URL-адресами), однако при нажатии на ссылку категории всегда отображается ошибка — Файл не найден (ошибка 404).

Я проверил, нет ли пробелов между символами URL. Ошибка относится к категориям страниц, информационные страницы в порядке.

Мой Htaccess выглядит так.

# 1.To use URL Alias you need to be running apache with mod_rewrite enabled.
# 2. In your opencart directory rename htaccess.txt to .htaccess.# For any support     issues please visit: http://www.opencart.com
