Products are not showing inside the VirtueMart shop

[rdymac]

Hi, I'm using Joomla 1.5.26 and VM 1.1.9 with the VM Demo Theme by Developing & Design

I have just noticed that the products are not being displayed inside the categories (but they appear inside the Random Products module and other modules). Categories are not showing anything at all.

I fixed the VM 1.1.9 category and subcategory issue. That's when I saw that the products are not there.

I have installed the Spanish Language for Joomla and VirtueMart.

Here is the link to the shop http://consumiblesokane.com

Please I need help!
