I am using PayPal Standard to process orders. I have the "Paypal Account Optional" feature set to on, which makes it possible to accept payments from customers who dont have paypal accounts. OpenCart is the shopping system that i am using.
This is the screen that is displayed when a customer want to purchase goods:
When you click the "Don't have a PayPal account?" link, the tab is expanded:
Is it possible to have this tab expanded by default, perhaps through the code that is sent to the site in the first place, with the order details?
I found out that PayPal stores a cookie when you log in. If you have a user on PayPal, it will show the "Log in" tab. If you have never used PayPal, or you have deleted the cookie, paypal will show the "Guest Payment" tab.
I can live with this, but it would still be nice to always have it show the Guest Payment by default.
