Fatal Error Call to undefined Method when returning to cart from paypal

Hello Everyone,

I have the Paypal for woocommerce plugin setup for paypal express, all seems to be working OK except when I return to the cart from paypal I am receiving the following error:

Fatal error: Call to undefined method WC_Order::get_discount_total() in /home/hairsilktresses/public_html/wp-content/plugins/paypal-for-woocommerce/classes/wc-gateway-calculations-angelleye.php on line 187

Does anyone know how to fix this? I tried reinstalling the plugin so far, no luck.

Best Regards,

Chris W.
