Previously, you suggested upgrading to version 8.2 to resolve conflicts and display errors. Elementor support recommended upgrading to version 8.3 instead. Symptoms: Compatibility issues and deprecated errors after upgrading to PHP 8.4.x. Questions: Should I upgrade to PHP version 8.2 or 8.3 to resolve the compatibility issues with WPML? Are there any known issues with WPML when using PHP 8.4.x?
