No aparece la página "Carro" en mi tema compatible con Woocommerce

Qué tal, tengo un serio problema con mi sitio web. Es: https://espirulinaperu.com , el tema es Vantage y dice que es compatible con Woocommerce. Sin embargo, tengo problemas, porque no me aparece la página /carro (ni /cart ni nada), ni tampoco la clásica /mi-cuenta ni otras que sí tengo en otras páginas donde también he usado Woocommerce.

No sé si hay un problema con los Enlaces permanentes, a mí me sale todo bien, el código de functions.php es:
