Looking at the HTML, all I can say is that there are no menu hikashop options found for your menus. That's why HikaShop cannot display the products as it doesn't know how it should display them.
In such case, it's actually using the default Display options of the configuration. The simplest will be to enable an existing "Associated products listing for category listing menu XXX" in the "Modules to display under the main area" option of the Display tab of the configuration and that should hopefully make it work.
Otherwise, you can always recreate your menus...
