PHP script not automatically updating when moved to another server

A friend built a ranking system on his site and I am trying to host in on mine via WordPress and Go Daddy. It updates for him but when I load it to my site, it works for 6 hours, but as soon as the reload is supposed to occur, it errors and I get a 500 timeout error.

His page is at: jeremynoeljohnson .com/yakezieclub

My page is currently at http://sweatingthebigstuff.com/yakezieclub but when you ?reload=1 it will give the error.

Any idea why this might be happening? Any settings that I might need to change?

Here is the top of the index.php file. I'm not sure which part of any of it is messing up. I literally uploaded the same code as him.

Here's the reload part:

$cachefile = "rankings.html";
$daycachefile = "rankings_history.xml";
$cachetime = (60 * 60) * 6; // every 6 hours, the cache refreshes
$daycachetime = (60 * 60) * 24; 
         // every 24 hours, the history will be written to 
         // - or whenever the page is requested after 24 hours has passed
$writenewdata = false;

if (!empty($_GET['reload']))
{
    if ($_GET['reload']== 1)
    {
        $cachetime = 1;
    }
}

if (!empty($_GET['reloadhistory']))
{
    if ($_GET['reloadhistory'] == 1)
    {
        $daycachetime = 1;
        $cachetime = 1;
    }
}

if (file_exists($daycachefile) && 
                       (time() - $daycachetime < filemtime($daycachefile)))
{
    // Do nothing
}
else
{
    $writenewdata = true;
    $cachetime = 1;
}

// Serve from the cache if it is younger than $cachetime
if (file_exists($cachefile) && (time() - $cachetime < filemtime($cachefile)))
{
    include($cachefile);
    echo "<!-- Cached ".date('jS F Y H:i', filemtime($cachefile))." -->";
    exit;
}
ob_start(); // start the output b开发者_如何学JAVAuffer

?>

I would check the permissions and path for the cache file as well as absolute paths to all the files
