PHPMAILER errors in logs

Hello again!

I am receiving the following errors in my PHP error logs.

Emails are sending just fine.

I’m running the latest version of phpList with PHP 7.4 and Ubuntu 24.04

[25-Mar-2023 10:39:10 America/Denver] PHP Notice:  Constant MANUALLY_PROCESS_BOUNCES already defined in /home/admin/public_html/lists/config/config.php on line 149

[25-Mar-2023 10:39:10 America/Denver] PHP Notice:  Constant PHPMAILER_SECURE already defined in /home/admin/public_html/lists/config/config.php on line 440

I have libphp-phpmailer installed.

I also have phpmailer installed with composer. (I don’t think I set this one up properly.)

Is there a possibility these are conflicting with each other?

Thank you!
Kevin
