help: whmcs autoauth not working..

WHMCS AuthAuth is not working (https://docs.whmcs.com/AutoAuth)

My Code: (auth.php)

<?php

$email = "******@galactic.host";
$goto = '../build.php';
/**
* Define WHMCS url and AuthKey from confguration.php
*/
$whmcsurl = "https://www.galactic.host/billing/dologin.php";
$autoauthkey = "*****"; //$autoauthkey from configuration.php

$timestamp = time(); //Get current timestamp
$hash = sha1($email . $timestamp . $autoauthkey); //Generate Hash
$email =
/**
* Generate AutoAuth URL & Redirect
*/
print("Attempting session handshake.. ");
$url = $whmcsurl . "? email=".urlencode($email)."&timestamp=$timestamp&hash=$hash&goto=" . urlencode($goto);
header("Location: $url");
print("Tele: $url ");

exit;


?>

Nothing is happening... The page stays blank, no errors, no redirect. any ideas?

Do you have php display errors enabled?

Do you have php display errors enabled?

How do I do that? Im running CPanel btw[DOUBLEPOST=1546278822][/DOUBLEPOST]Enabled errors got this:
Warning: Cannot modify header information - headers already sent by (output started at /home/galactic/public_html/auth.php:3) in /home/galactic/public_html/auth.php on line 24



LINE 24:
header("Location: $url");

You can't set HTTP headers if there is already output. More details here: https://stackoverflow.com/questions/8028957/how-to-fix-headers-already-sent-error-in-php

Easiest fix is just to use a JS redirect:

echo '<script>window.location.replace("'.$url.'");</script>';
