I changed the text to show the customer "Paypal" instead of "Paypal IPN" on the checking out pages. And deactivated the old paypal module. However now whenever I reach the page where they need to click "Confirm Order", it simply refreshes back to the same page, instead of proceeding on to the paypal page. What did I do wrong? Prior to the name change, it worked fine. But isn't it just a text change?
