[PHP] Na localhost (XAMPP) działa na serwerze nie. Opcje

[desavil]

Witam, mam taki skrypt:

[PHP] pobierz, plaintext 
<?php
$file_id = $_GET[file_id];
$file = $_GET[file];
$link = "http://xxx:xxx@hotfile.com/dl/$file_id/$file/";
 
$genlink = file_get_contents("http://hotfile.com/dl/$file_id/$file/");
$genlink_zmien = explode('<div class="arrow_down"><strong>Pobieranie:</strong> ', $genlink);
$genlink_zmien2 = explode(' <span>|</span> <strong>', $genlink_zmien[1]);
$genlink_zmien3 = explode(' MB</strong></div>', $genlink_zmien2[1]);
$size = 1024*1024*$genlink_zmien3[0];
 
$nazwa_pliku = $genlink_zmien2[0];
$nazwa_pliku_bezspacji = str_replace(" ","_",$nazwa_pliku);
$file_extension = strtolower(substr(strrchr($nazwa_pliku,"."),1));
switch($file_extension){
	case "exe": $ctype="application/octet-stream"; break;
	case "zip": $ctype="application/zip"; break;
	case "mp3": $ctype="audio/mpeg"; break;
	case "mpg": $ctype="video/mpeg"; break;
	case "flv": $ctype="video/flv"; break;
	default: $ctype="application/force-download";
}
 
$size2=$size-1;
header("Pragma: public"); // required
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: private",false);
header("Content-Type: $ctype");
header("Content-Disposition: attachment; filename=$nazwa_pliku_bezspacji");
header("Content-transfer-encoding: binary");
header("Content-Length: $size");
header("Content-Range: bytes $size2/$size");
@readfile($link);
exit;
?>

Na XAMMPie w localhost działa skrypt poprawnie, bez problemów się ściąga pliki, a na serwerze nie. Co jest nie tak?

Wywala taki błąd na serwerze www:
