Сайт www.smtmobile.me (сейчас тестируем). На денвере все работает.

Я не программист, поэтому прошу помощи как ее можно решить. Я понимаю, что ошибка где-то в базе данных. Но где и что нужно сделать???

У меня такая же проблема как и у sapollandrew

Частично решить её можно убиранием в запросе учета по акционной цене. Т.е. если будут акции на товар, то сортировать будет не по новой цене, а по изначальной.

(Действительно для OpenCart

В файле:


меняем строку

//$sql .= " ORDER BY (CASE WHEN special IS NOT NULL THEN special WHEN discount IS NOT NULL THEN discount ELSE p.price END)";


$sql .= " ORDER BY p.price";
