I am a new WHMCS user. I have a page at https://cloud.pagehackers.com/index.php?rp=/store/1 which contains several products, however I am unable to add them to the cart. When I click "Order Now," the browser simply redirects to the first group of products I have. This is true for product groups I add myself. However, I am able to add products installed from WHMCS MarketConnect: I added the RapidSSL offering and was successfully able to add it to my cart. Is there something that I'm missing when adding my products to WHMCS, or are my URLs problematic?
