Error Sending Emails using PHPMailer over SMTP - php

Question

I've had a look around as to why my PHP script was not sending any emails when I had the $mail->isSMTP(); set.
Before I go into the problem, I would like to point out that I am using mailgun.org as my SMTP server. My PHP script is simple, I have an HTML form that forwards data to a PHP file which in turn calls the PHPMailer script and sends an email.
Here is the code to my PHP Script:
date_default_timezone_set('Asia/Manila');
require 'phpmailer/PHPMailerAutoload.php';
// include 'phpmailer/class.phpmailer.php';
// require 'phpmailer/class.smtp.php';
$mail = new PHPMailer;
//$mail->isSMTP();
$mail->SMTPDebug = 0;
$mail->Debugoutput = 'html';
$mail->Host = "smtp.mailgun.org";
$mail->Port = 465;
$mail->SMTPAuth = true;
$mail->SMTPSecure = "ssl";
$mail->Username = ""; //Username removed
$mail->Password = ""; //Password removed
$mail->setFrom('', ''); //Email address and Name removed
$mail->addReplyTo($userMail, $firstName);
$mail->addAddress('emailOne#example.com', 'Name'); //Actual Values Changed
$mail->addAddress('emailTwo#example.com', 'Name'); //Actual Values Changed
$mail->addAddress('emailThree#example.com', 'Name'); //Actual Values Changed
$mail->Subject = 'New Application for website by '. $firstName;
$mail->msgHTML($theMessage);
$mail->AltBody = $theMessage;
if (!$mail->send()) {
echo "Mailer Error: " . $mail->ErrorInfo;
} else { //Some HTML code here
}
Now then, as you can see, I have commented out the $mail->isSMTP(); line. This is because whenever I try to use it, the code does not load, and after a long wait gives a 500 error. (Sadly, by cPanel setup does not allow me to view apache logs).
I tried importing just the class.phpmailer.php file, but that gave me a fatal error that the class SMTP was not defined, which was expected. I then included the class.smtp.php file which gave me the same 500 error.
I had a look around StackOverflow and came across this answer however it did not help my case.
I have had a look at Mailgun's logs, but they have no record of the script even trying to connect.
Additional Information: If it matters, I have the following files in the same directory:
- sendMail.php //The script above
- class.phpmailer.php
- class.smtp.php
- PHPMailerAutoload.php
- index.html //Not important in this situation.
I hope someone will be able to help me out, I'm relying on the non-smtp method for now. :/

Try this working fine..!
date_default_timezone_set('Asia/Manila');
require 'phpmailer/PHPMailerAutoload.php';
// include 'phpmailer/class.phpmailer.php';
// require 'phpmailer/class.smtp.php';
$mail = new PHPMailer();
$mail->IsSMTP();
$mail->SMTPDebug = 1;
$mail->SMTPAuth = true;
$mail->SMTPSecure = 'ssl';
$mail->Host = "smtp.gmail.com";
$mail->Port = 465;
$mail->Username = ""; //Username removed
$mail->Password = ""; //Password removed
$mail->addReplyTo($userMail, $firstName);
$mail->SetFrom('emailOne#example.com', 'my name');
$mail->Subject = 'New Application for website by '. $firstName;$mail->MsgHTML($theMessage);
$mail->AddAddress('aswad#yahoo.com', 'my name');
if($mail->Send()) {
echo "Message sent!";
}else {
echo "Mailer Error: " . $mail->ErrorInfo;
}
