Problem: Footer and header built with Elementor disappears after activating WPML or after a WPML update.
Solution: The solution is to delete a line in the class-header-footer-elementor.php. You can find it here: "wp-content\plugins\header-footer-elementor\inc\". The line is: require_once HFE_DIR . 'inc/compatibility/class-hfe-wpml-compatibility.php';
