I try to buy my own product using Paypal Express Checkout as a Guest. Everything going fine in Paypal Website. Then the process continue to my web site until step 3. After clicking Confirm, error appear on my website. I dont remember what is written there. Then until now i cant open my website.
My question is, how can i recover my website because i dont touch any coding before, my Paypal IPN is set up a year before and my customer can buy without any problem.
Is there any upgrade from zencart for Paypal IPN/Express checkout that i missed?
I really need help now because i dont know where to begin to troubleshoot my problem.
Im using 1.3.9h. My web is http://suteraterengganuonline.com
Thanks in advance.
