My store has been working very well except I ran across a very interesting problem. I have PayPal USA, Canada v. 1.3.4 installed, set up and working. I am having a problem with the PayPal module not showing up as a payment method if there are more than 10 unique items in a customers cart. I did recreate the problem. There is no error code or any information other than it just is not there. I have not found any other people with the same problem. I have no idea where to find a solution.
