 * Plugin is trying to load the following file and it is breaking the rest of the
   JavaScript on my admin screens:
    /wp-content/plugins/wordpress-seo/js/dist/chunks/
   51.js
 * Any idea why this is happening? Could you please provide a fix as soon as possible?
   It is stopping my team from working efficiently on the site?
 * Is it safe to upload the previous version 6.2?
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fjavascript-error-chunk-loading-failed%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * also had this issue with 6.3, there is no dist/chunks folder so the URL 404s.
 * Downgrading the plugin to 6.2 worked fine for me and fixes the problem.

 * Same problem on my web sites too. Even worse, two of those sites use Fail2Ban,
   so the repeated 404s end up locking out my clients from their web sites!

 * We recently released Yoast SEO 6.3.1 that includes a fix for this type of error.
   Please update your plugin and let us know if the issue remains.

 * Thanks!
 * I noticed though that the change log says, “This only affected users using a 
   locale different than en.” This does not seem to be true in my case. All of them
   have the following added by Yoast SEO…
 * `<meta property="og:locale" content="en_US" />`
 * Or does that change log refer to the less specific, and more generic “en” locale,
   with no country specifier? I guess it’s doesn’t matter as long as it is working
   now.
