Hey there, @crystella17! Thanks for contacting us. I’m happy to help you.
I checked your SSR and noticed you are using Elementor and Astra as your theme, correct?
As mentioned, this issue usually happens when something is overwriting Woo’s default email template.
This might be something you actively changed in the email template, it might be your theme doing it or it might be a plugin you have.
If you have not actively changed the email template, I suggest running a conflict test to see if the issue persists.
To test, you’ll first want to change the theme on your site to Storefront, then check to see if the issue is still present. If that resolves the issue, you’ll want to get in touch with your theme’s developer and see if they have an update or fix for you.
If changing the theme doesn’t help, you’ll want to deactivate all plugins except for WooCommerce (no other exceptions, including Elementor) and take a look. If that fixes the problem, re-enable the other plugins one by one (gradually), checking after each, to see where the issue is coming from.
— Be sure you have a good backup in place of your full site and database. You can ask your host for backup functionality or you can consider using a service like Jetpack. If something goes wrong, you will be able to restore it.
— Also, you can consider using a plugin like Health Check & Troubleshooting. This is a plugin developed by the WordPress community and it is helpful to disable plugins without affecting your current site visitors.
— It is important to consider as well a staging functionality in case you would not like to touch your production site (you can ask your host if they offer this service), or you can use WP Staging for quickly spinning up a new test site.
You can find more about this in this guide.
Please let us know about your findings.
Have a wonderful day!
