 * Hi!
 * Since the latest WP Update, all functions related to PHPMailer will result in
   a Fatal error:
 * `Fatal error: Uncaught TypeError: Argument 1 passed to WPCF_Email::mailer_config()
   must be an instance of PHPMailer, instance of WPMailSMTP\MailCatcherV6 given,
   called in /var/www/vhosts/crowdticket.saarland/httpdocs/wp-includes/class-wp-
   hook.php on line 287 and defined in /var/www/vhosts/crowdticket.saarland/httpdocs/

 * This occurs only, if the WP-Crowdfunding E-Mail Add-On is enabled.
 * What can I do?
