Have you linked your products to your main menu? You need to do this in your navigation to link your products to your online store. To add a menu item, you need to click Online Store > Navigation and click Main Menu in your admin. You will then need to click Add menu item and enter a name for the menu item. You will probably want to name it something like Products or Shop. Click the link field and select the product page you want to link. Click add to your save menu item and then save menu. Your product will then be linked to your main menu and accessible for your customers to shop.
