I have been using a server with php 4.4.1 and my script worked fine untill I had to move to another one with ver 5.1.4.

[code]
$Account = $_COOKIE['name'];
$Pass = $_COOKIE['pass'];

if ($Account == NULL || $Pass == NULL) { die("You must logged in to select a character. If you think you are logged in please<br>allow cookies and try again."); } [/code]

as mentioned it worked fine on 4.4.1, now in 5.1.4 it doesnt work, I always get the die message. any ideas, isset will work? I think I have tested isset but didnt work either, dont remember.

just a guess but try
[code=php:0]
if (($Account == NULL) || ($Pass == NULL)) {
    echo "You must logged in to select a character. If you think you are logged in please<br>allow cookies and try again.";
    exit;
}[/code]

I use something simiular to this for sessions. Not sure if it will work for cookies but give it a try.

[code=php:0]
if ((!$_COOKIE['name']) || (!$_COOKIE['pass'])) {
    echo "You must logged in to select a character. If you think you are logged in please<br>allow cookies and try again.";
    include('yourloginpage.php');
    exit;
}[/code]

You are certain the cookie is set on the client machine?
[/quote]Just realised that that's my actual problem.

[code]<?
setcookie("name", "Admin");
setcookie("pass", "Darn");
?>[/code]
This works fine but the code below doesn't, any ideas why?
