Could not instantiate mail function  is PHPMailer s way of reporting that the call to mail    in the Mail extension  failed   So you re using the  mail  mailer    You could try removing the  s before the calls to mail   in PHPMailer  MailSend and seeing what  if any  errors are being silently discarded

As noted here   This means that your PHP installation is not configured to call the mail   function correctly  e g  sendmail path is not set correctly in your php ini   or you have no local mail server installed and configured    In my case I had to allow the mail   function   activate the mail   queue   in the settings of my webhost
