definitely a CURL issue
Thanks for both going beyond the call of duty and for providing the tools to push the ISP on this point.
Back up and running mostly. Can you please check the shipping again - it looks like not all the options are working. Not sure what you updated last time so I cannot do it myself? When shipping overseas it refers to the following page "http://www.ridewerx.com/checkout_failure.php?shipping=fail" (screen shot below).
Also, when the transactions are completed the checkout success page says that the cart is empty rather than showing what you have bought. Is this a remaining CURL issue?
Much appreciated, Mark.
