I am also getting the same error message upon upgrading to WP 3.2:
PHP Fatal error: Cannot access protected property PHPMailer
I’ve done a little testing on my site, and this has been affecting real emails, as well as test emails.
I’m looking forward to a fix for this issue. Other than this small issue, I’ve been using the wp-mail-smtp plugin for a little while, and have had much better luck than the built in PHP mail function. Thank you for making a great plugin, Callum.
