Sorting Products

-- url of the page with the problem -- : www.be4eat.com/2014-08-07-17-33-22/biglietti-be4eat-2015-a
-- HikaShop version -- : 2.5.0
-- Joomla version -- : 3.3.3
-- PHP version -- : 5.5.29

in my shop all products are sorting by ID.
I have assigned for each product a code: 001, 002, 003, etc.
In the configuration panel I have selected as sort filed "product_code" but without success.
Where is the error? How can I do?

Hello,
To do what you want, you'll just have to sort your products directly through the Hikashop content module configuration page which have the ID number 172. You'll be able to access to that configuration page via "Hikashop->Display->Content moduels".
