 * Hi [@spiwee](https://wordpress.org/support/users/spiwee/)
 * We understand that you received an email from WordPress that there was a fatal
   error reported for the Yoast Duplicate Post plugin.
 * Sometimes, this happens when the plugin files are cached and some old files are
   still used after updating the plugin or when the plugin update couldn’t complete
   due to a server or connection hiccup. As a result of that, it causes missing 
   files in the relevant plugin, so you are emailed about an error.
 * On occasions, this causes temporary errors that resolve themselves once the cache
   has been cleared. If the problem doesn’t resolve for you automatically, can you
   please try clearing the cache from your theme, plugin, server, and CDN.
 * Are you able to access your website and are there no visible error messages that
   appear either in the frontend or in the WordPress admin dashboard? Could you 
   also check if your Yoast Duplicate Post plugin is on the latest version v4.1.2?
   If so, we wouldn’t be too concerned about it. However, if there are any error
   messages, please do let us know.

 * Hello
 * Thank you very much for your reply
 * I have no visible errors in WordPress dashboard or on the site
    The extension
   is in 4.1.2 So, I purged the cache. I think there is no need to do anything else
   Thanks again
 * Best regards
 * Nathalie
