Cart only pass transactions below $50
Is there any reason or code in the cart that by mistake I can set by mistake to only pass transactions below or up to a certain total amount in the cart? I'm asking that wired question because looks like the PayPal Payment pro and express are only approving transactions below $50 and I called PayPal no limits for transaction below 10K and also Virtual Terminal attached to the same account is processing any transaction amount up to 10K without problem. So I think is something in the cart code that I by mistake made it. I changed the SSL certificate on the host can this cause that problem?
I'm running crazy here and the customer is almost going bananas, keeping telling that the business is loosing money... WOW I'm really need help here
