Error WC_Cart::get_cart_url is deprecated since version 2.5! Use wc_get_cart_ur

Hi,

The cart of my website, is not previewing the products in the cart.

The other error, is when I add a coupon at checkout it gives this error:

wp-content/plugins/woocommerce/includes/wc-deprecated-functions.php:54 – WC_Cart::get_cart_url is deprecated since version 2.5! Use wc_get_cart_url instead.
require(‘wp-blog-header.php’), require_once(‘wp-includes/template-loader.php’), include(‘/themes/kakina/page.php’), get_template_part, locate_template, load_template, require(‘/themes/kakina/template-part-head.php’), kakina_header_cart, kakina_cart_link, WC_Legacy_Cart->get_cart_url, wc_deprecated_function, _deprecated_function

Anyone can help me please?
