 * Hey [@henk-barreveld](https://wordpress.org/support/users/henk-barreveld/)
 * Thank you for reporting this and for the kind words — glad you find the tool 
   useful!
 * You’re right that it’s not critical, but it’s definitely worth fixing. We’ve 
   passed the details along to our development team to investigate the PHP 8.3 deprecation
   notice in WPML_MessageSanitizer.php.
 * Thanks again for taking the time to let us know!
 * Have a good one!
