The plugin works well with wp 5.4, but when I update to wp 5.5 it doesn’t send the emails. In the logs I get:
[25-Aug-2020 19:35:48 UTC] PHP Warning: Cannot declare class PHPMailer, because the name is already in use in […]/public_html/wp-content/plugins/post-smtp/Postman/Phpmailer/PostsmtpMailer.php on line 24

I’d appreciate a little help so I can update my wp.
