Ah.. I see. So if you set one email address on your email setting it work just fine?
If this is the case, try to modify your "includes/helper-functions.php" file, search around line 475 - 491 for this code:
$has_email = false;
foreach ($email_address as $email){
$email = trim($email);
if(!empty($email)){
$mail->AddAddress($email);
$has_email = true;
}
}
if($has_email){
$send_status = $mail->Send();
$mail->ClearAddresses();
if($send_status !== true){
echo "Error sending email: ".$mail->ErrorInfo;
}
}
replace it with this one:
$has_email = false;
foreach ($email_address as $email){
$email = trim($email);
if(!empty($email)){
$mail->AddAddress($email);
$has_email = true;
$send_status = $mail->Send();
$mail->ClearAddresses();
}
}
You can now put two email address into your MachForm email setting and then test it again.
