uploade filer

Hej
Jeg har før uploadet billeder ved brug af følgende script:

    $files = $_FILES['upfil']['name'];
    $sti = "/imagearchive/";
    $dist = $_SERVER['DOCUMENT_ROOT']."$sti";
    move_uploaded_file($_FILES['upfil']['tmp_name'], $dist . $files);

Men nu får jeg pludselig fejlen:
Warning: move_uploaded_file() [function.move-uploaded-file]: SAFE MODE Restriction in effect. The script whose uid/gid is 3124/80 is not allowed to access / owned by uid/gid 0/0 in /usr/home/web/web45965/system/addimage.php on line 24
