Debug : IN DEBUG MODE NOT GET ERROR [error_count:protected] => 0

Answer 1

It would really help to read the docs and base your code on the examples provided, which show how to get info about errors, and show debug output. You're not getting any output because you're not asking for any. From the example in the readme:

if(!$mail->send()) {
    echo 'Message could not be sent.';
    echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
    echo 'Message has been sent';
}

That will show you the reason for any sending failure. To enable SMTP debug output, do this:

$mail->SMTPDebug = 2;
