I have tried installing the plugin for paypal express with the API Account Name, API Account Password and Signature that I received from PayPal and I get that purple box that pops up that gives you a bunch of directions.
However, when I reload the application and go to my cart, I have the option of clicking on a Checkout button which takes me to a page to fill in my billing address or I can click on a paypal checkout button and the page just reloads. Could you please tell me why the page just reloads after clicking on the paypal checkout button?
