All attempts to send SMTP mail are failing.
I generated a PHPMailer script to experiment with and had the same issue. However, their troubleshooting guide suggested that adding the following to the script might cure the problem temporarilly:
$mail->SMTPOptions = array(
'ssl' => array(
'verify_peer' => false,
'verify_peer_name' => false,
'allow_self_signed' => true
)
);
It worked!
Now I need to add the equivalent to this plug-in so that I can get the thing at least sending emails while I try to resolve the certificate issues.
I have attempted to add it to the plugin - but obviously not in the right place.
Can anyone suggest how I should go about this.
