It seems that a constant from Elementor—which we use on our WordPress portal—is being called, but it appears that this constant does not exist or is not defined. This issue has arisen after the latest update.
The error occurs in admin-ajax.php when saving or editing a table in TablePress. The changes are successfully applied, but the browser still returns a 500 Internal Server Error. I also checked the WordPress debug logs, and there is nothing related to TablePress or admin-ajax.php.
