Payment module problem (PayFast)

[livewire]

Hi

i have installed virtuemart in my local pc and im testing the payment module from PayFast https://www.payfast.co.za/c/std/virtuemart

There is a big problem that im facing. Once i test in sandbox mode (even live) once i click on confirm purchase it says

Thank you for your order!
Your order has been processed.

and the order has been added to the order list once the purchase is confirmed but not paid

secondly when im redirected to the payfast page i get this error

Error

The supplied variables are not according to specification: cancel_url : cancel_url must be a valid URL notify_url : notify_url must be a valid URL return_url : return_url must be a valid URL

im using the latest joomla and virtuemart versions. and any help will be appreciated

Ask the Payfast plugin supplier. Some plugins will not verify a sale when running in localhost.
