Hello,

Thanks for getting back.

I tried to check your product with Google’s Rich Results Test but due to some issue with your schema code, this tool is not able to test your page:

I was able to check it with the Structured Data Testing tool and there is an error with your MPN. It seems like some plugin or your theme is causing some issues with Rank Math’s schema code as our plugin doesn’t output the MPN field like this:

To determine which plugin is causing the conflict, please follow this troubleshooting guide:

Let us know if you find the culprit. We really look forward to helping you.

Hello,

Thank you for keeping in touch with us.

We might need to take a closer look at the settings. Please edit the first post on this ticket and include your WordPress login in the designated Sensitive Data section.

It is completely secure and only our support staff has access to that section. If you want, you can use the below plugin to generate a temporary login URL to your website and share that with us instead:

You can use the above plugin in conjunction with the WP Security Audit Log to monitor what changes our staff might make on your website (if any):

Hello,

Thanks for getting back. Sorry for the delay and any inconvenience that might have been caused due to that.

I checked and noticed that you were using an old version of Rank Math. I have updated your WordPress and Rank Math to the latest version. After that, I was able to check your site with the Rich Results Test and the Product schema added by Rank Math is working fine and there is no error related to MPN.

So you can ignore the results of the structured data test as that tool is outdated and Google no longer recommends using that. You can check your site here with the Rich Results Test: https://search.google.com/test/rich-results

However, your page is still not eligible for rich results as the schema added by Stamped plugin is throwing an error: Missing field ‘name’

Please contact their support team and get their help in resolving the issue. Also, I noticed that you are using old versions of most of the plugins on your site. I would recommend updating all of the plugins to the latest version to avoid any conflicts and performance issues.

Hope this helps. Let us know if you need any further assistance.
