    Hi @nzsimonyoung,

    For some reason, your WP installation uses the global phpmailer class installed on your server (in /usr/share/php/libphp-phpmailer/class.phpmailer.php), and not the one provided by WordPress.
    The one distributed with WordPress is modified a bit and loads the SMTP class from within the WP code base.

    Please remove libphp-phpmailer package from your Ubuntu (Debian or whatever) installation – this should fix the issue.

    Hi Slava,

    when I first installed your plugin it wouldn’t work same error (class not found), and the /usr/share/php/libphp-phpmailer/ was already there, I’m assuming installed as part of the build process. But thinking the problem was that Phpmailer wasn’t installed, i ran the installer for that. But the problem didn’t go away. And thats when I posted the question on here.

    So if I rename the libphp-phpmailer folder, it breaks my whole wordpress and I can’t log on at all and log file shows
    PHP Warning: require_once(/usr/share/php/libphp-phpmailer/class.phpmailer.php)

    using my backup I rolled the server back to before I installed phpmailer, but I’m still having the same error.

    Uncaught Error: Class ‘SMTP’ not found in /usr/share/php/libphp-phpmailer/class.phpmailer.php

    so not sure how to get WP to use the modified code you mention

    Regards
    Simon

    Hi Slava,

    I gave up, and started again from a fresh VM and reinstalled everything, And WP Mail works fine this time

    Regards
