Hi @nastaia ,
Thank you for your reply.
I have tested disabling the plugin and enabling it back but the issues are still there.
Following is the log:
PHP: 2022-10-03 16:39:21 [error X 14][/home/fengsh14/public_html/wp-content/plugins/elementor-pro/modules/woocommerce/widgets/purchase-summary.php::1636] Uncaught Error: Call to undefined method Automattic\WooCommerce\Admin\Overrides\OrderRefund::get_order_key() in /home/fengsh14/public_html/wp-content/plugins/elementor-pro/modules/woocommerce/widgets/purchase-summary.php:1636
Do you have any ideal?
