I’m having the same problem. The donation does not appear in my post types.
My host is GoDaddy. There are no negative messages. And I get this positive message in Settings: Congratulations! Your site appears compatible with PayPal’s requirements.

Basically, it’s failing when attempting to establish a connection to PayPal. As far as I can tell, the libraries PayPal tells us to check for seem to be correct, but it’s not clear what else might be an issue. PayPal certainly doesn’t seem to like something it’s getting from GoDaddy. That’s at the hosting level, not at the plugin.
