It seems like the issue might be related to your site not being properly verified or connected with Google services. First, ensure your site is publicly accessible and that you’ve set up the correct WordPress and Site Kit configurations. Clear your browser cache and cookies, then try again. If the issue persists, check your WordPress REST API by visiting yoursite.com/wp-json/ to ensure it’s functioning correctly, as Site Kit relies on it. Also, verify that there are no plugins or security settings blocking access. These steps should help resolve the issue and restore your site’s health for proper Google Site Kit functioning.
