Hi @arieljoquico,
Thanks for reaching out. This error is as a result of both Site Kit and another plugin loads what’s called a Google Charts Library script on the same WordPress dashboard. We do have a solution out for next with the next release of Site Kit. In the meantime, what you can do is view Site Kit data from the main Site Kit dashboard, and not the Site Kit widget on the main WordPress dashboard.
You can also hide the Site Kit widget if you wish, on the main WordPress dashboard, so the error doesn’t appear. You can then activate it once more after the plugins next release, due next week.
If you’d like me to check for the other plugin that is also loading the same Google Chart Library script feel free to share your Site Health information and I can inspect your set up.
@meulie While the same applies for you, I’d be happy to check your site set up if you want to share your Site Health information after creating an individual support topic. Thank you!
