I am using version 1.5.0. I am testing express checkout in paypal sandbox.

I tried testing the send IPN through paypal sandbox. However it does not show in the orders or PayPal Instant Payment Notifications section within the zencart control panel.

When I try to buy something from my website, I get the following error message -

“ An error occurred when I tried to contact the payment processor. Please try again, select an alternate payment method, or contact the store owner for assistance. () - (35) error:14094410:SSL routines:SSL3_READ_BYTES:sslv3 alert handshake failure ”

I have already entered the user name, passwords & API signature in the administrator section. And entered the handler information in paypal.

What am I doing wrong ?
