This means that you have not set a terms and condition page in WooCommerce.
Go to WooCommerce ---> Settings ---> Advanced and then go to the Page Setup section and make sure you have set a Terms and Condition page there.
If you do have set a page there, go and check (under your Pages section in the WordPress dashboard) that your page that contains your terms and condition information has the Status: Published.
