PayPal payments received, but orders not showing up in ZC

[DrByte]

I then went ahead and switched to Express Checkout. The reason I didn't use it before was because I didn't like the way it promoted PayPal with the big orange express checkout buttons. But I was able to easily get rid of those by modding to override files. By also disabling all the "Express" options in the Express Checkout Module admin, it now looks and feels exactly like my old Website Payments Standard module.

Just be aware that doing so is contrary to PayPal's integration requirements.

But I guess this module isn't prone to silent errors.

Correct. The silent errors that the Standard/IPN module suffers from do not cause the missing-orders problems when using Express Checkout.
