 * Hi,
    updating to 16.2 from 16.1.1 breaks the WordPress page editor. When trying
   to access e. g. /wp-admin/post.php?post=1246&action=edit, it says: “The editor
   has encountered an unexpected error.”

 * Hello,
 * We are sorry about the error. Can you please delete the Yoast SEO free and clear
   cache and reinstall it?
 * Also, ensure that your theme and other plugins are updated.

 * Thanks for your reply. I tried that w/o any success. Same error. My installation
   is up-to-date.

 * Thanks for the feedback.
 * Just to be sure, we would like to rule out any plugin or theme conflicts that
   may occur. The fastest way to do this is to **deactivate all non-Yoast plugins
   and switch to a standard theme** like [Twenty Nineteen](https://wordpress.org/themes/twentynineteen/).
 * Test this on your development or staging site, if you have one. If not, we recommend
   using the [Health Check & Troubleshooting](https://wordpress.org/plugins/health-check/)
   plugin. This plugin allows you to run a conflict check **without affecting normal
   visitors to your site**.
 * As we can imagine that you’re unfamiliar with checking for conflicts, we’d like
   to point you to a step-by-step guide that will walk you through the process: 
   [How to check for plugin conflicts](https://kb.yoast.com/kb/how-to-check-for-plugin-conflicts/).
 * If you do not feel comfortable to do this yourself or if this does not solve 
   your issue, our [Yoast SEO Premium plugin](https://yoast.com/wordpress/plugins/seo/)
   comes with one year of (technical) support.

 * Thanks. It turned out that Yoast SEO 16.2 is incompatibel with Relative URL plugin(
   [https://wordpress.org/plugins/relative-url/](https://wordpress.org/plugins/relative-url/)).
   This plugin removes the hostname. It seems that 16.2 does a regex check on URLs
   and throws this JavaScript error: “An error occurred while running ‘mapSelect’:
   URL constructor: / is not a valid URL.”

 * Thanks for the feedback.
 * Additionally, we highly recommend reporting plugin conflicts to the developer
   of the conflicting plugin as they may have additional information vital to providing
   a resolution. Having both teams work on the issue is a benefit to you.
