PHPMailer issue after upgrade to WP 5.5/5.6

    Hi all,
    I hope to get your kindly support because I’m facing a strange problem on one of my site; I tried several tips after many hours spent reading posts and suggestions wthout success.

    After upgrading to WP 5.5 (and of course to 5.6) I’m getting error every time I try to use the PHPMailer function. If I rollback to WP 5.4.4 everything work well.

    This is the error:
    AH01215: PHP Fatal error: Cannot declare class PHPMailer\\PHPMailer\\PHPMailer, because the name is already in use in /web/htdocs/www.trakracer.it/home/wp-includes/PHPMailer/PHPMailer.php on line 32

    I tried also to use a SMTP Mail plugin but still happens. From email logs, the email seems sent without problems but instead I don’t get it.

    The issue is related to Woocommerce (4.8 installed) too. The customers are not able to finalize the order because they get stuck on checkout page, even the order is placed to the backend. They are also not able to recover password or doing anything related to email functions; the same thing happens to website’s admins.

    The installed theme is Porto; PHP is 7.3.22.
    I’ve another store with exactly the same plugins, hosting and PHP version and it works well with WP 5.6.

    Here’s site health info:

    Hi @il_magnus. Sorry that we missed your post.

    I hope that you managed to resolve this issue. In general, this is a WordPress issue rather than a WooCommerce one, and the first thing to check would be that all your plugins and your theme is up to date.

    If that doesn’t help, you might want to do some conflict testing.

    Hi @il_magnus,

    We haven’t heard from you in a while so I’m going to go ahead and mark this thread as resolved. If you still need help with this issue or have any other questions about the WooCommerce plugin, please start a new thread.
