Your theme has bundled outdated copies of WooCommerce template files

Hi there, this is very urgent. We are a company, and our whole site is down. We were changing content and we are now stuck in Under Construction mode and can’t get out. It seems that the problem may be “HighendWP/woocommerce/cart/cart.php version 2.3.0 is out of date. The core version is 2.3.8,” Please help!!!!!!
