site kit error

Hello @realpano thanks for opening a support topic with us. We have seen previous reports of this linked to caching and optimize plugins. An example can be seen here caused by the SiteGround Optimizer plugin. I’d be happy to look at this further for you if you could share the following:

1. Your Site Health information. You can use this form to share privately if preferred. 
2. Does this error appear consistently for you, on the Site Kit main dashboard, on the Site Kit widget on the main WordPress dashboard, or when using the Site Kit admin toolbar?
3. When checking the Site Kit dashboard from a Chrome browser?incognito window?does the same occur? If so, please share any?browser console errors?that appear.?

We also have an open GitHub issue for this where you can follow for updates. Let me know here if you have any questions on the above information.

As we didn’t receive a response I’ll mark this as resolved. Feel free to?open a new support topic?if you continue to encounter issues, or reopen this topic and we’d be happy to assist.
