You must provide at least one recipient email address. PHP mailer - php

Question

I'm currently experiencing a very strange issue trying to set up a simple mailer from a form. I've literally used the code on many sites seems to be working fine. But on this particular one I seem to be getting the Error "You must provide at least one recipient email address."
This is the code that i've been using
<?php
require_once('class.phpmailer.php');
$name = $_POST['name'];
$user_email= $_POST['email'];
$query = $_POST['message'];
$message = file_get_contents('email.html');
$message = str_replace('{{name}}', $name, $message);
$message = str_replace('{{email}}', $user_email, $message);
$message = str_replace('{{message}}', $query, $message);
$email = new PHPMailer();
$email->CharSet = 'UTF-8';
$email->IsHTML(true);
$email->From = $user_email;
$email->FromName = $name;
$email->Subject = 'Talking Together Speech Therapy Enquiry From- '. $name;
$email->Body = $message;
$email->AddAddress( 'barry.tickle12#gmail.com​' );
if($email->send()){
// Trigger when email sends
}else{
//Trigger when email doesn't send
echo $email->ErrorInfo;
}
?>
Can a specific server setup be causing this? Other sites on the same server seem to be working fine with it apart from this particular one.
* Edit *
Var dumped all POST Requests to the file and nothing is being returned empty.

Answer 1

Maybe add a check to see that you have all the required data ?
$email= $_POST['email'] ?? '';
if($email){
/** Your code goes inside this if */
} else {
/** Show error */
}

Answer 2

Try using new version of AddAddress():
$email->addAddress('recipient#domain.com', 'Name');
