Just have the same problem with Contact Form 7 and just commented one line of the file mail.php and it works.

The file is in wordpress/wp-content/plugins/contact-form-7/
It’s named mail.php
The line 171 contains

add_action( 'phpmailer_init', 'wpcf7_phpmailer_init' );

I just change it to

//add_action( 'phpmailer_init', 'wpcf7_phpmailer_init' );
