[Resuelto] The Elementor Editor is not working when WPML is active

We have updated recently on our Staging environment Elementor (3.18.3) and WPML to their latest versions.

The Elementor Editor is not working anymore at least in our environment when WPML is active.

The main problem is the slug /en added by WPML and taken by Elementor.

Interestingly older version of Elementor and WPML work fine on our production environment, where the SITE URL is
enlace oculto and the HOME URL is enlace oculto

enlace oculto

But on staging after update it only works when SITE URL = HOME URL. As soon as WPML is active our HOME URL will always have /en slug

Elementor tries to loads elements with /en slug which fails: enlace oculto
