How to fix page redirects?

Question

JavaScript

Hello! There is an online store on wordpress + woocommerce, which has a problem when switching to an empty cart - the transition page loops and gives the corresponding error. If you put at least 1 product, then looping does not occur and everything fulfills the norms. In the cart settings, the personal account page of the installed Theme My Login plugin is selected , in which the cart shortcode is added. What could be the reason and how can it be seen and corrected?

Found a solution! The whole point is that if the cart and checkout shortcodes are located on the same page, then when the cart is empty (if you go to the checkout page, a redirect is triggered), this results in a cyclic redirect. Fixed in the wc_template_redirect() function , which is located in
this piece is removed

// When on the checkout with an empty cart, redirect to cart page
   elseif ( is_page( wc_get_page_id( 'checkout' ) ) && sizeof( WC()->cart->get_cart() ) == 0 && empty( $wp->query_vars['order-pay'] ) && ! isset( $wp->query_vars['order-received'] ) ) {
     wp_redirect( get_permalink( wc_get_page_id( 'cart' ) ) );
     exit;
   }
