Fresh install of Joomla and HikaShop. Data from an older instance of HikaShop (2.6.4) was copied over from the production site. Categories and subcategories will list just fine on frontend, but not any products.

I can access a specific product through the browser's address bar (e.g. test.grandprix-software-central.com/inde.../product/94-gprm-pro ), but not by selecting its category. I can access categories and products just fine through the backend.

I've tried using the default Beez3 and Prostar templates (and corresponding module position changes), but get the same result.

Not quite sure how I did it, but I got the products listing fine now. Was playing around with CSS and noticed that some inline CSS was coming from a menu option. Opened that up and saw a Products Option tab. Toyed with that and it started to work. Certainly not intuitive.
