Fatal error: Uncaught exception ‘phpmailerException’ with message ‘Invalid address: ‘

You are receiving this error because you have not specified at least one recipient for the notification email. To fix this, open process.php and enter an email address for the $config['recipients'] setting. For example:

$config['recipients'] = 'me@example.com';
$config['recipients'] = 'me@example.com';
