woocommerce cart and checkout in blank

Hello, greetings. I am building my site, but I have noticed that it does not display the cart page or the checkout page; it shows a blank page.

I’ve tried permanent links, deleting and recreating both pages, but it still doesn’t work.

Would I need to purchase another plugin to make it work?
I’d really appreciate it if you could take a look. Here’s my info.

Thanks in advance.
