 * Hello [@mauromandala](https://wordpress.org/support/users/mauromandala/),
 * Thank you for bringing this to our attention.
 * 
   These warnings are related to undefined array keys in the Site Mailer plugin
   and are appearing due to compatibility changes in PHP 8.3. We’re aware of the
   issue and will be releasing a fix soon to ensure compatibility with the latest
   PHP version.
 * 
   In the meantime, if you’d like to hide these warnings from the frontend and 
   login screen, you can temporarily disable WP_DEBUG in your wp-config.php file
   by setting it to false:define( ‘WP_DEBUG’, false );
 * 
   We appreciate your patience and understanding as we work on resolving this.Best
   regards,
