I'm getting this error 10736 too often. I was going to switch to PayPal exclusively -- but this error code is bad news for business. I don't know what to do. I've fiddled with the settings, but it keeps coming back.
I'm using ZenCart v1.5.1 on an apache linux server. I'm using the PayPal Express Checkout (NVP 84.0).
