I got the Paypal checkout button to work. This is how I did it......
1. Open the checkout page. 2. Go to windows and open server behaviors if not on your panel. 3. Click on Authenthication for paypal express checkout and check the field where it says ReturnURL* and the CancelURL* and see if says [url]http://localhost.... or your http://wwwyourdomain.com/. I uploaded mysite to my host so I changed it to http://www.mydomain.com/pp_checkout_.... 4. uncheck the check box which says "Use paypal sandbox server for testing"
I'm still having problems with the paypal direct payment.
Have you gotten anywhere with any of this yet?
