Thanks for reaching out @codescribler. If you’re already tried the “Redo the plugin setup” button, you can reset Site Kit in order to setup the plugin once more (Tools > Available Tools > Reset Site Kit).
We also have a guide on the plugin website in relation to this error that contains more details on this. Note that be resetting, you will need to connect all previously connected modules once more.
It’s no longer sending data to google analytics.
It’s possible that you have no Analytics snippet on your site, and therefore no data being collected. While the screenshot you kindly shared doesn’t indicate whether there is or was an Analytics snippet on your site, if you have the Analytics module connected within Site Kit and you run into data errors, the issue may be limited to data appearing within Site Kit. It’s possible that data is still being gathered in Analytics in such cases.
If you encounter any further errors after resetting Site Kit, please share your Site Health information along with any such errors. We can then troubleshoot this further. Thank you!
