I am seeing the same code depreciation errors in my WP debug log as was reported (and resolved) with regard to PHP version 8.2 here: https://wordpress.org/support/topic/depreciation-warning-php-8-2/ I’m on PHP version 8.3, Post SMPT Version 3.9.5 “PHP Deprecated: Creation of dynamic property Postman_Zend_Mail_Protocol_Smtp_Auth_Crammd5::$_username is deprecated in…” Hello @pennymachines , Thank you for reporting this. This is the same Creation of dynamic property deprecation in Crammd5.php (lines 53 and 56) that was previously addressed for PHP 8.2. It appears the fix needs to be extended for PHP 8.3 compatibility as well. This has been forwarded to our technical team for review. They’ll ensure the properties ( $_username , $_password ) are properly declared in the Postman_Zend_Mail_Protocol_Smtp_Auth_Crammd5 class to fully resolve the deprecation across all PHP versions. We’ll update this thread once there is a fix. Thank you for your patience! Thank you. Hello @pennymachines , I appreciate your paitence. I am pleased to inform you that our team has implemented a fix. Could you please download the beta version from here and test it on your end? Download Beta Once you’ve had a chance to test it, please share your feedback and let us know if everything works as expected. Thank you for your patience and for helping us improve the plugin! Hi @pennymachines Just Wanted to follow up with you regarding the fix we provided. Have you had the chance to test it? We’re waiting for your feedback. Thank You
