Paypal IPN error - wrong e-mail address

[Moncia]

Ok - I've done what you asked.

But it is only some of the customers who experience this, I've had two contacted me, and the others are doing fine.

But I got this message today when entering the admin/module/payment section,

CURL functions not found - required for Linkpoint API payment module

I have also been contacted by a customer. In spite of the error having the term IPN its from the use of the express checkout. I say this because I do not have PayPal IPN turned on.
1. What version of Zen Cart are you using? (1.3.7)
2. Which PayPal module are you using? (Express)
3. What have you used for the email address in configuring your PayPal module?(Not used in the express module)
4. Have you turned on Debug Logging? What's in the log files/emails ?(yes see attachment and PM for password.)

This problem has occured at my site lately too, It seems like it's those who want to pay using their own paypal account who excpreience this problem. Everything is configured right, and my primary e-mail adress is correct, but still they get this error message:

"We cannot process this transaction because there is a problem with the
PayPal email address supplied by the seller. Please contact the seller to
resolve the problem. When you have the correct email address, payment can be
made at www.paypal.com."

This is very frustrating because I have new customers everyday. It's so strange because I haven't done any changes since I started.
