Updated Joomla to 3.3.6 and Hikashop business 2.3.

-- HikaShop version -- : Updated to HikaShop Business: 2.3.3
-- Joomla version -- : 3.3.6
-- PHP version -- : 5.4.32
-- Browser(s) name and version -- : Chrome Version 38.0.2125.104 m

Updated both Joomla to 3.3.6 from 3.3.1 and HikaShop Business: to 2.3.3
The site now has lost the products when selected in the Category listing.
The url is updated to the product list, but nothing appears and still shows the category listing.

Any help would be appreciated.
Regards and thanks in advance.
