Hello,
list of files that should be updated you can find in WooCommerce > System Status. I’ve checked your site and see that you see the outdated files massage because of form-edit-address.php file in parent theme, as you may see in theme changelog – woocommerce/myaccount/ ( form-change-password.php, form-edit-address.php, my-account.php ) files were deleted, so simply delete these files to solve the issue. If next time you’ll see files directly from the child theme then you need to compare parent theme file and child theme file that is out of date and place into child theme file the necessary changes from parent theme file.
Server environment: MySQL version: 5.5.44 – Recommended minimum requirement is MySQL version 5.6. See: WordPress requirements
– this notice relates to woocommerce, and if server provider can’t upgrade MySQL version, please simply ignore the message.
Regards
