Category Content Module (list) 404 Error

Have created a module to list categories.

The display shows fine BUT any time I click on the category link I get a 404 error.
What am I missing?

Module params are here: screencast.com/t/fkfAxnzrKK

URL example: domain.com/category/12-ebooks.html

Hi,

Can you please :
1. Tell me if you're using a SEF extension ? if that's the case can you try it without it ?
2. Give me a link to your website for testing purpose ?

Thank you .

1. Using core SEF only
2. luznews.com/_j3/ see right side "Shop" module.

Please select another category listing menu item like the default one which is created in the hikashop default menus of the joomla menu manager and that should help.
