  • Hello,

    Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.

    This warnings usually come up with Product schema. I checked your site and there seems to be product schema added to your pages, however, doesn’t seem to be from Rank math

    Assuming you are using the latest version of all the plugins and the themes (please update if not yet), it is coming from one of the plugins or the theme you are using.

    To determine that, while checking your testing your page(s) here:, please follow this troubleshooting guide:

    Only the site admin would know and your users won’t be affected by this troubleshooting.

    Thank you.

    I was able to check your site and the product schema, which is what is bringing up the issues you have noted is coming form the plugin WP Product Review Lite. You can confirm this by disabling this plugin temporarily then test your URL here:
    Hope this helps
