Does your WordPress WooCommerce site keep saying enter address, while address has been entered already?
You’ve probably used Checkout Field Editor to disable the country input field and are now confusing WooCommerce when it’s trying to process the order
The validation message “Please enter an address to continue” normally shows when you are trying to place an order where shipping details is needed, but “shipping_country” is missing there. Please make sure that you have not disabled or removed the shipping_country (billing_country in case of shipping to billing address) field in your checkout form.
If you are selling only to a specific country, you can use the WooCommerce default settings for defining selling and shipping locations instead of disabling or deleting the country field.
