Changed review to 5 stars.

@metrotechs While I didn’t see a support topic created whereby we could assist it’s possible there may be other plugins or plugin conflicts impacting your front end styling. You’ll see from this support topic one such case, related to minification using a caching plugin.

Can you share your site URL and we can investigate? Alternatively you can disable the Site Kit admin bar using the following, added to your themes functions.php or preferabley a custom plugin.

add_filter( 'googlesitekit_show_admin_bar_menu', '__return_false', 1000 );

Looking forward to your response.

@metrotechs We’ve narrowed down the issue to a conflict with version 1.7.0 and the WP External Links plugin. We’re reaching out to the authors of that plugin for a fix, so we can keep you updated on the progress.

@metrotechs WP External Links has released a new version 2.45 which addresses the issue with broken CSS while viewing the site logged in. Please update their plugin if you’re using it and let us know if it helps.

@metrotechs I’m following up to see if you have had an opportunity to try the latest version of Site Kit? It would be great to know if your experience has improved.
