Problem: If you're experiencing a warning message about an undefined property in the Astra theme's extras.php file while configuring WPML, specifically related to stdClass::$menu_id on lines 508 and 546. Solution: We recommend checking if the menu_id property exists in the $args object using isset() to avoid the error when the property is undefined. You can temporarily update the following lines in the /wp-content/themes/astra/inc/extras.php file:
if (isset($args->menu_id) && in_array($args->menu_id, $astra_menu_locations)) {
This solution might be irrelevant if it's outdated or not applicable to your case. We highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If the issue persists, please open a new support ticket at WPML support forum.
