THOSE ARE ERRORS IN LOG FILE
[Thu Oct 30 13:42:16 2003] [error] PHP Warning: session_start(): Cannot send session cookie - headers already sent by (output started at file.php:3) in file.php on line 5
[Thu Oct 30 13:42:16 2003] [error] PHP Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at /file.php:3) in file.php on line 5

THIS IS THE BEGINING OF file.php 5th line is 'session_start()'

session_cache_limiter('public');
session_start();
ob_start ();

What´s wrong? Thanks in advance for an answer.

Note: If you are using cookie-based sessions, you must call session_start() before anything is outputted to the browser.

If session_start() is the 5th line, what are the first four lines?

Thanks for your quick answers. I´m not using cookies and the first lines are comments.
Users have no problem to view this file.

oke let me rephrase the quote from the php.net website....

GENERALLY session_start() MUST be called absolutely BEFORE anything else in the script

[edit-- humor me and try swapping those first 2 function calls..... --]

consequently....

OK. I'll do this. But I really cannot understand why I get this error message from this certain file while I have a lot with the same begining.... Tomorrow I´ll get a new log file. Thanks!
