PayPal API Error -- totals of the cart item amounts do not match order amounts

[edwiny]

I am using Prestashop 1.4.7.0 and PayPal Module v 2.8.6.

 

I have sporadically gotten the following error with various attempted customer purchases. Customer is unable to checkout and pay with PayPal.

 

I read some of older posts regarding this same issue but the problem originated from an older version of Prestshop and PayPal module. I believe I have the most current versions.

 

 

I would greatly appreciate it if anyone within this esteemed forum can lend a hand and offer guidance.
