I’m having a hard time, with the illdy theme, the checkout page doesn’t show the radio button to choose the payment method.
The printscreen ‘finalizar-compra (1)’ is the Storefront Woocommerce theme, taht have the radio button, and the ‘finalizar-compra (2)’ is the illdy theme, that doesn’t show the radio and checkbox.
I have checked the page and the CSS is being interrupted, could you please try disabling your third party plugins then check to see if the alignment is corrected.
