Hi,
First, check if your products have a weight. If not they are considered "virtual products" and if the "force shipping regardless of weight" setting is turned off in the Hikashop configuration, the shipping method won't appear for them on the checkout.
Then, make sure that you still have the "shipping" view in the "checkout workflow" editor of the HikaShop configuration.
If you removed it, then no shipping method selection will appear on the checkout.
Finally, also check the "include virtual product prices" setting of your shipping methods. If your products don't have a weight and that setting is turned off, then the products price won't be taken into account for the min/max price restriction settings of your shipping methods.
