So I get this when I go to checkout. I'm using paypal Website payments pro. The module is active and all the info from the paypal site inputted in the admin section. The SSL cert is installed and the URL on the checkout page is showing https:// and the lock icon shows up. Anybody know what the problem is? Thanks!
