Неработает сортировка товаров и фильтр

Einshtein · 24 травня 2012

Господа, доброе утро!

Недавно обнаружил что перестала работать сортировка товаров и фильтр в категориях.

При попытке что либо отсортировать или отфильтровать - пишет просто "Найдено товаров: 0 за 0.067 сек. / Показано с 0 по 0 из 0 (всего 0 страниц)"

В файле /catalog/model/catalog/product.php вроде всё впорядке (на сколько помню, последнее время файл не правил и не заменял):
