Paypal Integration Error

[Aakash Tomar]

I have installed and configured the paypal USA & Canada module with prestashop.

 

the first image is when proceeding the paypal payment.

 

 the second image is when receiving the error while connecting.

 

 

 

I have already generated Paypal payment api signatures and have enabled with the module. already tested with sandbox test. All was working fine. Problem arises when going live mode.

 

I stuck and do not know what to do now.

 

I have checked module configuration and signature settings so many times and not able to rectify the problem and solution for the same. Kindly advise for the same.

 

Thanks in advance.
