I’m running trunk and the current version of WP Mail SMTP. When the plugin is active the following error occurs In frontend and backend on most pages.
Deprecated: 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. in /sites/xxxxxx.net/files/wp-includes/functions.php on line 4921
I’m reasonably certain it’s related to https://core.trac.wordpress.org/changeset/48035
