PHP 7.0, getting “Cannot Redeclare class PHPMailer”

  • basically as explained in the title. I get the following error:
    Fatal error: Cannot declare class PHPMailer, because the name is already in use in /var/www/html/wp-includes/class-phpmailer.php on line 28

    Looks like you are re-declaring the existing class. I did a diff on the two version, and I couldn’t find any significant changes

    I tracked this down to an error with the theme having a phpmailer as well. The theme also declare PHPmailer. Do you have a way to not re-declare PHP mailer?

    The only way I could get this to work (I’m no PHP / WP expert) was to take your PHPMailer class and rename it PHPMailer2, then adjust all places that were extending PHPMailer to PHPMailer2. I then commented out the phpmailerException deceleration. Not sure if this will actually allow me to use the plugin, though. So far it doesn’t crash my website which is good

    Same problem, there is already a class-phpmailer.php in standard wordpress 4.7.4, so I am not even sure it’s needed to have PHP included in this plugin.

    Hi, WordPress includes a customized version of PHPMailer that doesn’t support OAuth2. That’s why the plugin needs to include the full PHPMailer library to support the OAuth2 feature.

    I have another SMTP plugin that doesn’t include the PHPMailer library. However, It uses username/password authentication instead of Oauth2.

    Hello ,

    And what is the solution if we want to use OAuth2 feature ?
