When a signed customer fills in the four-steps-checkout-process: Personal Information Address Delivery Option Payment Then is not possible to move to step 3 after completing well the address and clicking "Continue" button, the page just refresh itself and nothing else happen, no delivery option is shown and no errors neither. The site has configured 3 carriers (1 Pickup in store which is free and other 2 are not free). Any ideas?
