Hi Andy,

I think the problem is with Paypal, when I turn to live model in Paypal, it indicates "Internal Error".

Hi Datakick, I understand what you mean now, and try again, find that the error is "currency not supported" as attached, it seems South African Rand is not supported by Paypal, what should I do so those clients using Visa Card or Mastercard could make the payment online?
