Error on accounts page

Hi. Hoping someone can help – I’m getting a Fatal Error when I click in “My Account” on the site I am building. https://crowdedhousesa.co.za/my-account/

Fatal error: Call to a member function populate() on a non-object in /home/crowdedh/public_html/wp-content/themes/unity/woocommerce/myaccount/my-orders.php on line 45

any help appreciated
