Fatal error: Call to undefined method WooCommerce

Hello,

My customers get this error when placing an order.

Fatal error: Call to undefined method WooCommerce::add_error() in /home/erensen1982/public_html/wp-content/plugins/woocommerce-beanstream-payment-gateway/woocommerce-gateway-beanstream.php on line 273

My theme and all plugins are up to date.

I already contacted beanstream they say the plugin currently works without any problem and it might be Woocommerce ralated issue. Looked for it online and everybody say reinstall woocommerce.

Please find my web site info below

Thank you for your time reading this.

Regards
