When content is deleted in WordPress, the default behavior is to return a 404 (Not Found) status code. However, according to HTTP specifications, a 410 (Gone) status code is more appropriate for resources that have been permanently deleted and will not return.
This plugin automatically returns a 410 status code for: 
 – Deleted posts 
 – Deleted pages 
 – Deleted custom post types 
 – Deleted users 
 – Deleted media attachments
Once activated, the plugin works automatically. When a visitor tries to access a URL that previously contained content but has been deleted or moved to trash, they will receive:
<ul>
<li>A 410 HTTP status code in the response headers</li>
<li>The standard WordPress 404 page template (customizable via your theme)</li>
</ul>

After the plugin update, the shortcode used in CF7 forms was removed. As a result, it is now displayed as plain text inside the form.
When releasing such updates, it is important to provide migrations and maintain backward compatibility. If functionality is removed, a fallback or automatic replacement mechanism should be left in place to avoid breaking existing forms.
