Hi Hikashop support

I am using Hikashop Business + Hikamarket. When I installed and worked few days with my temaplate everything was ok. But when I added new categories suddenly products stopped displaying in category listing. I deleted the categories I have previously added but it does not help.

I have already read:
www.hikashop.com/support/documentation/67.html#categories_menu
and all posts about this topic on Your forum. I have spent serveral hours trying to fix this issue.
I think I understand concept of the associated moduls to display products yet it is still not working.

My website is: s339467542.domenastandartowa.pl/db2/index.php/shop

Please help. I will gladly create a config user for You and send any other access neeeded thru priv.

Thank You
Tim

I found it out (at least partially) this is not hikashop - it is template issue.
When I change tempalte to Joomla Standard one it is working.

Thank You
Tim
