 * Hello [@travelanddo](https://wordpress.org/support/users/travelanddo/) thanks
   for reaching out and sharing the error you are seeing. We have seen [this error previously](https://github.com/google/site-kit-wp/issues/4449)
   caused by a conflict with the WP Rocket plugin. That previous issue was addressed
   but this could be the result of a conflict with another third party plugin on
   your site.
 * To start, could you please follow the troubleshooting steps [here](https://sitekit.withgoogle.com/documentation/troubleshooting/using-troubleshooting-mode/)
   to see if you experience the same while in troubleshooting mode with just Site
   Kit active? If you continue to see the error then please could you also share
   your [Site Health Information](https://imgur.com/Rtkmsba) using this [private form](https://docs.google.com/forms/d/1lhjns2K7c0Ny7ME4gxTcsnYtNUtcMr8BvFpPQi23Y1E/edit)
   and I can look into this further.

 * [@travelanddo](https://wordpress.org/support/users/travelanddo/) I just wanted
   to check in once more with you to see if you are still having issues? If you 
   are please can you share the requested information above and I will be happy 
   to help.
