Hi,
Upon checking the system report, it appears the email templates override the default. The email template override is most commonly used through the theme.
You can consider the following in this case:
1. Update issues: Overriding WooCommerce email templates may lead to issues when WooCommerce or related plugins are updated. New updates might bring new features, bug fixes, or changes in the default email templates, and if you’ve overridden them, those changes won’t be applied automatically to your custom email templates, leading to potential compatibility issues.
2. Maintenance and troubleshooting: Overriding WooCommerce email templates requires manual modifications in the email template files as you create, edit, or customize templates. Making it harder to isolate the cause of any problems.
3. Inconsistency and branding: Creating custom email templates may result in inconsistencies in your store’s branding, design, or functionality if changes are not carefully implemented.
I’d recommend taking these actions:
1. Switch to a default theme, such as Twenty Twenty or Storefront.
2. Deactivate all plugins except for WooCommerce, then reactivate them individually to identify the problematic one. Test the feature after each activation and deactivation. Further information on the conflict test can be found here. (As mentioned previously).
Also, you can reinstall WooCommerce to prevent any email template customizations. Prior to conducting this test, be sure to create a complete backup of your site. More information on installing and uninstalling WooCommerce can be found here.
Let us know how that goes for you.
