After credit card payment went through, error message occur

[asgc]

I"m using DPS_PxPay_v1.3 for the credit card payment.

 

When i try to purchase item from the website and fill out the credit card page. It will return to checkout_confirmation.php. Once i clicked the "confirm order" at the right bottom page, it keep return back to the credit card payment interface.

 

Meanwhile i will receive an e-mail saying:

 

Payment could not be completed - reference not found

 

Invalid length for a Base-64 char array.

 

Is there something wrong with the code??

 

Please help. Thank you

Still waiting for the help.

 

Tried to search the forum but non of them works.

 

It seems after the merchant completed, it's not return to checkout_success.php but keep going back to checkout_confirmation.php

 

The SSL in configuration.php under catalog and admin are set on false.

 

I've tried to change the general.php and checkout_success.php with tep_redirect

 

but non of them works.
