Hi William, glad to hear you got the plugin up and running fast.
1) Two solutions to this:
a) You can uncheck the “Use WordPress Mailing System” checkbox so the plugin will use a simple PHP mailer to email and it will have you name correctly.
b) You can change the name that appears on emails going out from WordPress in your WordPress settings.
2) The shopping cart should automatically get cleared out when customers return to your site after payment.. if this is not happening then we will have to investigate what is going wrong. Most likely a post payment clear step is failing so it’s not clearing the cart.
Do you see any error or warning on the “Thank You” page after you return from PayPal?
