Fatal Error: Uncaught Error

    Hi there
    Have been running this plugin (connected to Brevo account) for nearly two years with no issues, but all of a sudden on Friday we got a fatal error without anything being done on the backend (no updates/changes to configuration/setting/backend etc). I can provide a screenshot but the error says:

    Fatal error: uncaught error: Failed opening required ‘/usr/www/users[xxxxxx]/wp-includes/PHPMailer/PHPMailer.php’ (include_path=’.:/usr/share/php’)
    in /usr/www/users[xxxxxx]/wp-content/plugins/wp-mail-smtp/src/Core.php on line 933

    I have deleted the plugin so that the site doesn’t break, but as soon as I try and reinstall/activate it, this error shows again.

    Any ideas? As I said, nothing has changed on the site at all to make this happen.

    Any assistance would be much appreciated.

    Thank you.

    Hi @nataliecary,

    Thanks so much for reaching out!

    Based on the error message you shared, it appears the plugin is attempting to access a file within WordPress core that’s either missing or not loading properly: /wp-includes/PHPMailer/PHPMailer.php. This file is a part of the WordPress core, so a few things could be happening here, and I’d suggest the following steps:

    1. Update WordPress Core Files
    This error might indicate that a core WordPress file went missing or wasn’t loaded correctly, possibly due to a partial update or file corruption. Please try reinstalling WordPress core files, which can often resolve issues with missing or corrupted files without affecting your content. Here’s a guide on how to do this: https://ww.wp.xz.cn/support/article/updating-wordpress/

    2. Reinstall WP Mail SMTP
    After reinstalling the WordPress core files, I recommend deleting WP Mail SMTP from your site entirely (if it’s not already removed), then reinstalling the latest version from the plugin repository. Here’s the link to download WP Mail SMTP directly from ww.wp.xz.cn: https://ww.wp.xz.cn/plugins/wp-mail-smtp/

    3. Check PHP Version Compatibility
    WP Mail SMTP requires PHP 7.3 or higher. If your site’s PHP version is below this, updating to a compatible PHP version can often resolve unexpected errors. You can confirm and update your PHP version in your hosting account or with assistance from your hosting provider.

    4. Ensure Brevo Connection is Active
    After reinstalling the plugin, you may need to reconnect it to your Brevo account, especially if there was any disruption due to the missing file. Our setup guide here will walk you through connecting WP Mail SMTP with Brevo again, if needed:
    https://wpmailsmtp.com/docs/how-to-set-up-the-brevo-mailer-in-wp-mail-smtp/

    If these steps don’t fully resolve the issue, could you share a bit more detail to help us investigate further? Here’s what would be helpful:

    • The PHP version running on your site.
    • Server error logs that correspond to the times when the fatal error occurred, as these can provide additional clues.
    • Any recent plugin or theme installations (even if inactive), as they can sometimes impact other plugins.

    I hope this helps to get things sorted! Thanks 🙂

    Hi Nukak,

    Thank you so much for getting back to me! We figured out the problem earlier today – it was a permissions issue with the PHPMailer.php file.

    Thanks again for getting back to me.
