Guest Checkout not working | WordPress.org

Hello community,

I’m quite new to the whole wordpress and woocommerce world. But I can’t seem to get guest checkout to work. I’ve enabled the option in the advanced tab but the buttons in the shopping cart only redirect to the home page.
But when logged in, the buttons work just fine and redirect to the cart page and checkout page.
I’ve looked around the forums for solutions but nothing works yet.

Does anyone know how to fix this?
