I setup Mijireh Checkout, it's the only Payment Gateway I have setup. It's the default Gateway. When I click the Proceed to Checkout button from the cart it doesn't take me to the Mijireh Checkout. It takes me to the regular WooCommerce checkout page, and the payment section is shaded out and has and spinning ajax style icon in the middle of it. How do I get the cart to send me to Mijireh Checkout?
