Hello. I used a WordPress Woo Commerce theme, Organic, to set up a website for a client. I used a table rate shipping plugin and we set up shipping rates according to the total amount spent. For some reason this is not holding. Table rate shipping is selected as the shipping method and it is enabled. But when shoppers get ready to check out, either no shipping amount is applied to their purchase or they get a message saying that no shipping methods are available. Can anyone tell me why this is happening? Thanks.
