This error occured when i am trying to access my admin panel of website on localhost server here is the code of my admin panel index.php

 <?php 
error_reporting(E_ALL);
ini_set('display_errors', 1);


$http_header = 'http://';
if (!empty($_SERVER['HTTPS'])) {
    $http_header = 'https://';
}
$this_url   = $http_header . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];

$this_url = str_replace('admin-panel', 'admin-cp', $this_url);
header("Location: $this_url");
exit();
?>
You can access the admin panel, from <a href="<?php echo $this_url ?>"><?php echo $this_url ?></a>

Answer

Solution:

Try testing for admin-panel in the URL before redirecting, like this:

if (strpos($this_url, 'admin-panel') !== false)
{
    $this_url = str_replace('admin-panel', 'admin-cp', $this_url);
    header("Location: $this_url");
    exit();
}

If str_replace('admin-panel', 'admin-cp', $this_url) fails, $this_url remains unchanged. If header redirects to the same page you will get an error like "unable to handle request 500 clear your cookies", or something similar.
