I don’t even know why you’re using Javascript for this

<?php
/* Redirect browser */
header("Location: http://whatever.com/php/userpanel.php");
 
/* Make sure that code below does not get executed when we redirect. */
exit;
?>

This is just one posibility of the thousands available. Probably yours will work too if you use the full address, me thinks

I mean, if you’re login in, you’d be checking that the account exists and name and password are correct. This is a job for the PHP script, not for Javascript (exceptions made if you use Node.js but then, why would you use PHP?)

Snippet from userlogin.php

 if($row>0) {
	$_SESSION['user'] = $uname;
echo "Login Successfully";
}

Snippet from userlogin.js

    success: function(data) {
        
	$('input#uname').val('');
  $('input#upass').val('');
		
          alert(data);
          $('#disp').html(data).fadeOut(2000);
          if (data == "Login Successfully") {
            window.location.replace("userpanel.php"); // here //window.location.replace("php/userpanel.php");  is not working

          };

this is a relative link, does it exist at all? does the /php folder is a publicly (by HTTP) available path/URL?

Using PHP Header function is really easy to get the redirect working. Just make sure Nothing is outputted before the header function or it will crash.
