Session Error

Hi,

the following php-snippet:

<?
// Fahrzeugverwaltung
// index.php
session_start();

// user-check
if (!isset($_SESSION['status']))
{
session_write_close();
header("Location: login.php");
}

[...]

?>

produces:

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /kunden/crea.de/webseiten/kunden/hmwa/index.php:1) in //webseiten/kunden/index.php on line 4

(Linux System)

I don't see, where a "<?" or two comment-lines could cause a header-output?

Thank you for any help!

Do you have short tags enabled in your php.ini?
If not, <? should be <?php and <? would be the start of output.

Thank you David - but (unfortunaly) the short tag in on.
