Your theme (XStore Child) contains copies of outdated WooCommerce template files. These files may need updating to ensure they are compatible with the current WooCommerce version. Suggestions to fix this:
Update your theme to the latest version. If there is no update available contact the author of your theme and ask them about compatibility with the current version of WooCommerce.
If you have copied over a template file to edit something, then you need to copy the new version of the template and apply the changes again.
