I'm trying to set up my PayPal payment gateway for my new WooCommerce store and I'm having big issues. I would prefer to use the express checkout button, but neither it nor the standard PayPal method is working. I've connected both of them to my PayPal business account using my API credentials, and I have the settings all enabled to display the express checkout button on the cart and the single product pages. I save the changes in the WooCommerce settings, refresh the cache and still nothing on the front end. No payment methods show up either on the cart, single product or checkout pages. I don't understand what could be going wrong. The theme I'm running is OceanWP and I'm running the latest version of WordPress and WooCommerce.
