There are no shipping methods available. Please double check your address, or co

Hi,

On my website I’m receiving this error when I’m trying to pay a product: “There are no shipping methods available. Please double check your address, or contact us if you need any help.”. I have no idea why this problem appeared.

For a category of products I’m using your plugin to create a Flat rate. For the products from that category I don’t receive the error, just on the products from the other categories.

Thank you for your support!
