 * We use the Ele Custom Skin plugin on two sites. Both of them recently threw fatal
   errors when autoupdated to the newest version of WordPress. After reverting to
   an earlier version of WordPress, attempting to update Elementor, Elementor Pro
   or Ele Custom Skin also causes a fatal error.
 * Fatal error: Uncaught Error: Class ‘ElementorPro\Core\Utils’ not found in /public_html/
   wp-content/plugins/ele-custom-skin/theme-builder/conditions/loop.php:39
 * Thanks for your help!

 * Hey there
 * I just had the same error, It seems elementor pro changed the namespace of its
   classes. I did the following to fix this:
 * Open wp-content/plugins/ele-custom-skin/theme-builder/conditions/loop.php
    On
   line 5 it says: “use ElementorPro\Core\Utils;”
 * Change this to:
    use “ElementorPro\Classes\Utils;”
 * Hopefully this is fixed in the next update of this plugin.

 * Heyy [@denisdebacker](https://wordpress.org/support/users/denisdebacker/),
 * The same has happened to me and I did what you said, but now my Elementor Pro
   keeps loading…
 * Any piece of advice?
 * Cheers mate!

 * Hey [@jpzenker](https://wordpress.org/support/users/jpzenker/)
 * Hard to say, the problem above always gives an error so the problem should lie
   elsewhere now. Be sure to check your logs for any hints.
