Fatal Error with Woocomerce

Bonjour,

Depuis la dernière mise à jour j’ai cette erreur quand j’essaie d’ajouter un produit au panier (quand ajax est désactivé)

Fatal error: Uncaught Error: Call to undefined method WC_Cart::get_tax_price_display_mode() in /home/clients/jbedev38200/prod/sywell/wp-content/plugins/colissimo-delivery-integration/includes/WC-colissimo-shipping-zone.php:549 Stack trace: #0 /home/clients/jbedev38200/prod/sywell/wp-content/plugins/colissimo-delivery-integration/includes/WC-colissimo-shipping-zone.php(252): Class_Colissimo_Shipping_Function->calculate_shipping(Array, Object(Class_Colissimo_Shipping)) #1 /home/clients/jbedev38200/prod/sywell/wp-content/plugins/woocommerce/includes/abstracts/abstract-wc-shipping-method.php(233): Class_Colissimo_Shipping->calculate_shipping(Array) #2 /home/clients/jbedev38200/prod/sywell/wp-content/plugins/woocommerce/includes/class-wc-shipping.php(345): WC_Shipping_Method->get_rates_for_package(Array) #3 /home/clients/jbedev38200/prod/sywell/wp-content/plugins/woocommerce/includes/class-wc-shipping.php(260): WC_Shipping->calculate_shipping_for_package(Array, 0) #4 /home/clients/jbedev38200/prod/sywell/wp-content/plugins/woo in /home/clients/jbedev38200/prod/sywell/wp-content/plugins/colissimo-delivery-integration/includes/WC-colissimo-shipping-zone.php on line 549

Cela bloque donc tout mon site… 🙁 Auriez-vous une idée ?
