With any child theme, plugins and updates like Woocommerce can fall behind in versions inevitably creating an issue at one time or another. It’s important to keep up with these updates so errors you find out from customers keep them from coming back.
How to update Woocommerce Form-Pay.php:
Search for the latest Form-Pay.php version and replace the new updated code with old code in Cpanel file manager and drill down to woocommerce -> checkout ->form pay
and take it from there. Your Checkout out process should appear a little sleeker and function much better.
