Reply To: Issue in CHECKOUT page

Hello,

Please, provide your site admin access (insert the site credentials into the Private content block under the message area) and confirm the permission for plugins deactivation, switching to the parent or default theme. This testing may take up to 15 minutes. You would better make the full backup of your site.

You can edit the checkout fields in the Appearance > Customize > Woocommerce > Checkout.

Best Regards
