help!! headers error when redirecting..

[gabrielkolbe]

Hi I get this error..

[quote]Warning: unlink(../logos/): Is a directory in /home/public_html/include_cs/functions.php on line 1710

Warning: Cannot modify header information - headers already sent by (output started at /home/public_html/include_cs/functions.php:1710) in /home/public_html/include_cs/functions.php on line 1714[/quote]

[code] $query="SELECT * FROM site2 WHERE user_id = '".$_SESSION['user_id']."'";
$result = mysql_query($query) or die(mysql_error());
while ($row = mysql_fetch_object($result)) {unlink("../logos/".$row->logo.""); }

$sql="UPDATE site2 set logo = '' WHERE user_id = '".$_SESSION['user_id']."'";
mysql_query($sql) or die(mysql_error());
header("Location: index.php?action=personalise_header");[/code]

I know there is not suppose to be any code before the header that are printed , there are none!! this is a simple deletion script, it deletes a picture then get redirected.

If somone has any advice to see if something IS printed please let me know..
Regards
