For sensible reasons, not all of us upgrade Wordpress the moment a new version is released.
So I was surprised to find that, today, my website was no longer able to send SMTP emails when nothing on the server had changed… except I found that SMTP Mailer had been upgraded to 1.1.18 and, when sending email, would fail with the following error:
[16-Apr-2025 18:44:29 UTC] PHP Warning: require_once(/home/xxxx/public_html/wp-includes/class-wp-phpmailer.php): Failed to open stream: No such file or directory in /home/xxxx/public_html/wp-content/plugins/smtp-mailer/main.php on line 586[16-Apr-2025 18:44:29 UTC] PHP Fatal error: Uncaught Error: Failed opening required ‘/home/xxxx/public_html/wp-includes/class-wp-phpmailer.php’ (include_path=’.:/opt/cpanel/ea-php82/root/usr/share/pear’) in /home/xxxxx/public_html/wp-content/plugins/smtp-mailer/main.php:586
Version 1.1.18 assumes that wp-includes/class-wp-phpmailer.php is available on previous versions of Wordpress… it isn’t … and the plugin fails because this file does not exist.

In the world of WP plugins, it’s easy to get bogged down by bloated, feature-rich options. This plugin is a refreshing departure from that trend. It’s lean, mean, and focused on doing one thing exceptionally well: sending emails.

Not working with Hetzner Servers.If I try other Plugins with same credentials everything works fine.

Set up fields were checked and double checked and each field was correct. Plugin never sent the 3 test emails we tried to send. If you want to waste time, as we did, then install, activate and try to send a test email with this plug in.
