Support » Plugin: WP Mail SMTP by WPForms » Emails not sending correctly from Toolset

  • Resolved jaimon82


    I have been experimenting issues with the sending emails (like a lot of people, I can see for the forum). In my case the problem is with Toolset email notifications.

    It worked fine until latests updates of WP and your plugin.

    Please, help with this.
    It’s pretty urgent.

    The error code is:
    Got error ‘PHP
    message: PHP Fatal error: Cannot declare class PHPMailer\\PHPMailer\\SMTP, because
    the name is already in use in /home/andaluciafilm/www/wpincludes/
    PHPMailer/SMTP.php on line 30’, referer:

    Hi @jaimon82,

    The latest version of WP Mail SMTP is absolutely compatible with new WordPress update. It looks like any of your plugins possibly the Toolset email notification or your theme is not compatible with WordPress 5.5. Please follow this troubleshooting guide to identify the incompatible plugin/theme that is creating the error.

    I hope this helps!



    Hi @sanzeeb3 thanks for your kind reply.

    Actually I think the problem wasn’t Toolset, or any other plugin.
    I changed to another SMTP plugin and it works perfectly.

    So, anyway, thank you!
