Hello,
Module is not showing any product.
I tried any option in Joomla cpanel but nothing.
Module is running on test site : frontiermerchandise.it/storia/
Thank you

Hi,

I don't know why this CSS rule is exist in your joomla template, but please follow my steps:

Open this CSS file:
frontiermerchandise.it/storia/templates/justbusiness-fjt/css/style2.css

And find this CSS rule:
div.panel
{
height:20px;
display:none;
width: 90px;
float:right;
text-align: right;
cursor:pointer;
padding-left: 20px;
}

Delete this CSS rule, completely.
Because it is effecting our product slider module, and it also has display:hidden rule, which hides the items in the slider.
I also notice a JAVA conflict issue in your website which is created by this JS file: NivooSlider.js
I believe it is the slideshow you are using. For testing purposes, unpublished that and try again. If still no luck, then try the another module position. Lets say, try the "horizontal" layout..

Try my suggestions and then let me know.

Cheers.
