AkeebaBackup is working fine. However, Query Monitor has displayed this message:

Message:
File class-phpmailer.php is deprecated since version 5.5.0! Use wp-includes/PHPMailer/PHPMailer.php instead. The PHPMailer class has been moved to wp-includes/PHPMailer subdirectory and now uses the PHPMailer\PHPMailer namespace.
