If you look at the product page screen captures sent in my previous response you will see that all three products have a weight of 1 gram. We never wanted to use weight as shipping parameter, as we are using a flat rate. However, after reading some information in the forums I added the 1 gram weight parameter to well over one hundred products, even though they will all have flat rate shipping. I re-tested. This did not solve the problem, that is why I posted this issue. Additionally, I already had the "Force shipping regardless of weight" option set to "Yes". I did not have the "Include virtual" option set to "Yes", as these are not virtual products and they already had the 1 gram weight added to the product information. However, I did change the setting for "Include virtual" and re-tested. This did not solve the issue. To take it a little further before I responded. I went into the same three products in the previous post and changed the volume on each to 1x1x1 mm. Since these products have dimensions, although they don't have a "volume" per se, this doesn't make much sense, but I thought I would try it anyway. I re-tested. Still have the same problem. Also, in Advanced Settings, I tried setting "Use AJAX when possible for Add to basket buttons" to "Yes" and "No", neither had any effect and the issue remains. I've attached another screenshot to demonstrate that the shipping continues to not work correctly. I've used other Joomla web shops, with up to 40,000 products. This is the first Hikashop that I've tried to set up. I chose Hikashop because people say it is more simple. However, I'm spending an awful lot of time trying to get a very simple shop set up with Hikashop.
