Problem with content module [closed]

Don't know why but now it seems to work!

-- HikaShop version -- : last
-- Joomla version -- : 3.2

Hello,
I have a problem with the content module used to link to categories.
The module shows correctly the categories, but when I click on one of that I get a white page!
Note that if I came from menu link, and I click on a category, I'm directed to this link that works perfectly:
energado.com/lista/category/12-borse-solare-fotovolataico
If I click on module's link I'm directed tu this link, that give me a white page:
energado.com/component/hikashop/category...volataico?Itemid=604

What can I do?

Thank you for helping me!
