Hey Nicolas,

So, when I switch to a different template it works well.
But, I don't have listing.php file in html/com_hikashop/category and even more than that, I have removed the com_hikashop directory comletely from /template_name/html and it still doesn't work with the template I'm using.

Link to page

Thanks

Can't beleive it but the CSS guy added this :

div#hikashop_category_information_module_.hikashop_category_information.hikashop_products_listing_main {
display: none !important;}

No wonder products were not showing...
