Как починить «корзину» Shopkeeper?

Question

[Игорь]

Здравствуйте
Есть один древний сайт на Evo 1.0.10 + Shopkeeper 1.3.4, проблема возникает при изменении количества товаров в корзине. Не подскажите, куда копать?
Суть:
Если попытаться изменить количество товаров в корзине, то сниппет отображения товаров просто выдает код своего вызова в текстовом виде [[SK_custom? &type=`product`]]
Причем корзина работает, при перезагрузке страницы по F5 все изменения считаются и сниппет нормально отображается.

Код SK_custom под спойлером
