It would better if you would leave an actual support request instead of a 2 star review when asking for help.
Our plugin provides lots of different PayPal products. For regular PayPal payments you want to enable Express Checkout. This will let you add PayPal buttons to the product pages, cart page, and WooCommerce checkout page based on your settings.
For direct credit cards you’ll use Payments Pro. You need to make sure you have PayPal Pro enabled on your account before you will be able to use it live. Are you sure you have this feature enabled on your account?
I’m happy to help you figure all of this out, but I sure hope you’ll adjust this review accordingly.
