Can not read properties

Thanks for reaching out @birisigenc. Based on the error and details you provided, this looks to be a conflict based on a third party plugin configuration. If you’d like to share the following we can determine more on this:

1. Your Site Health information. You can use this form to share privately if preferred.??
2. 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.?

Note that we are aware of other reports of this, in particular when using Siteground’s Optimizer plugin and a minification configuration, as per this previous support topic:

We received a Site Health information form response that references this support topic. Assuming this was from you, I can see you have the SiteGround Optimizer plugin active. Can you temporarily deactivate this plugin and share whether you encounter the same error when checking the Site Kit dashboard?

If the error doesn’t occur with SiteGround Optimizer temporarily deactivated, you can go ahead and activate this once more. After activating, please check your configurations, as I suspect you have minificaiton enabled. If so, you can remove Site Kit resources from minification (SiteGround Optimizer settings > Front end optimization > General > Exclude from HTML minification). The directory you need to add is /wp-content/plugins/google-site-kit.

After making that changed please save your settings and check the Site Kit dashboard once more for the error.

Let me know how you get on with the above.

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.
