Glitch

I have a jewelry store. I put in a few pieces of jewelry to see how it looks. The next day it says, “The selected shipping method of this product is no longer available.” So I took out all the jewelry and went with many different vendors. I filled the store with a lot of jewelry. The next day it said the same thing, “The selected shipping method for this product is no longer available.” How could so many vendors all of a sudden not offer the shipping that they stated they allowed? I filled the store with over 20 products, and they ALL said that. There was no way that all of them wouldn’t allow it. So either I didn’t set up the back correctly, or the plugin glitches. Another website I own had a glitch with the plugin.
