When customer checks out. Billing address is filled out. When press "place order"  goes back up and asks for address details. Order does not go through

If i press add a different shipping address even if it is the same as the billing address the order is placed

I have two card payment gateways it is the same for both.

Thanks for prompt response.

Not at all. Structure is fine.

I want the billing address to work when I press place order without Checking Shipping box. Currently cannot place order without checking Shipping address box.

If press place order without Shipping address order is not placed and takes me back to  billing address to add address

If I give you access will you be able to try it yourself. In Sandbox mode? 

Same problem when using both payment gateways viz Walletdoc and Payfast.

I dont want to remove the shipping option. I want both billing and shipping options. In some cases the addresses are not the same. I want shipping to default to billing address.

I have checked this box but it is not working.
