categories dont link to products

-- url of the page with the problem -- : mywebsite.com/mypage
-- HikaShop version -- : 2.3.0
-- Joomla version -- : 3.3.0
-- PHP version -- : 5.3

Hello i am kind of puzzled with one configuration. Any category menu i create links to products pages. I can see the produts in categories, but the links to each product wont work.

I have spent a view hours trying to figure out... but no luck.
