NZ payment express(DPS) module error after approved by DPS transactions

[allnz]

Dear all,

 

 

I am a new prestashop user who live in NZ and install free DPS Payment express module as payment gateway.

 

However, the version of DPS module is bit old so I think the DPS module is not working with Prestashop 1.6.0.9.

 

When transaction is approved by DPS and then I click next for return to my site but  error -  "Cart cannot be loaded or an order has already been placed using this cart" is displayed

 

So, I have a looked error php file which is validation.php.

 

The validation.php contain order-confirmation.php but Prestashop 1.6.0.9 dosen't have order-confirmation.php

 

 

 

How can I fix this problem??

 

 

Please give me some information how to fix this??

 

Many thanks advance.

 

 

 

Regards,

 

Sam
