(Using a ctrl-r refresh on the site, and with the dev tools open, which I assume flushes the browser cache like Chrome) * Their mac is a bit older, running macOS 11.78, and its in Safari 14.1.3. * We tested and with 21.7 it was working on their Chrome browser, but it isn’t their main driver so I needed to find an immediate solution for them. * On my Macbook Pro / macOS 13.5 / Safari 16.6 it was working fine on 21.7, I didn’t test it as I was rolling each version back. * Hopefully this helps you dig into the actual issue? - This reply was modified 2 years, 5 months ago by [rtpHarry](https://wordpress.org/support/users/rtpharry/). * [rtpHarry](https://wordpress.org/support/users/rtpharry/) * (@rtpharry) * [2 years, 5 months ago](https://wordpress.org/support/topic/yoast-editor-not-loading-js-console-errors/#post-17273853) * For others with this issue, I have started my own thread because this one is marked as resolved and also Yoast staff haven’t been acknowledging it since the first reply: * [https://wordpress.org/support/topic/yoast-panel-not-displaying-on-safari-14/](https://wordpress.org/support/topic/yoast-panel-not-displaying-on-safari-14/) Viewing 8 replies - 1 through 8 (of 8 total) The topic ‘Yoast Editor Not Loading – JS Console Errors’ is closed to new replies. * ![](https://ps.w.org/wordpress-seo/assets/icon-256x256.gif?rev=3419908) * [Yoast SEO - Advanced SEO with real-time guidance and built-in AI](https://wordpress.org/plugins/wordpress-seo/) * [Frequently Asked Questions](https://wordpress.org/plugins/wordpress-seo/#faq) * [Support Threads](https://wordpress.org/support/plugin/wordpress-seo/) * [Active Topics](https://wordpress.org/support/plugin/wordpress-seo/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/wordpress-seo/unresolved/) * [Reviews](https://wordpress.org/support/plugin/wordpress-seo/reviews/) * 8 replies * 5 participants * Last reply from: [rtpHarry](https://wordpress.org/support/users/rtpharry/) * Last activity: [2 years, 5 months ago](https://wordpress.org/support/topic/yoast-editor-not-loading-js-console-errors/#post-17273853) * Status: resolved
