I got this exact same problem! I just get this error 3 times, it reports about lines 158, 159 and 160. On those lines is this code:


setcookie("username", "Ceox");
setcookie("password", "ceox1");
header("location: page.php");

// *****************************************************************************
// Purpose redirects to other PHP page specified URL ( $url )
// Inputs $url
// Remarks this function uses header
// Returns nothing

i have these lines here :
function Redirect( $url )
{
header("Location: ".str_replace(array("\r\n",'%0d%0a',"\n",'%0a',"\r",'%0d'),'',$url));
exit;
}

be sure that there is no html before you redirect the page. the error usually occurs when there is already an html sent as header to the server.

[Ceox]

No HTML before that on my page.

[muhammad shahid]

but how i eliminate this error.

[wspeeckaert]

Make sure there are NO blank lines, or text of any kind before <?php

[Ceox]

Oh shoot, I had HTML before that through an echo function!
So that has to be away from there?

If this is literally your script
>i have these lines here :
needs commenting.

Please use code tags when posting code so we can see what the actual script is.

Ceox,
This error can be caused by a few things. You've kind of hijacked muhammad's thead with your version of the problem.

But in answer to your question, header info has to be the very first thing output to the page, as said no HTML, spaces or anything!

[Ceox]

Oh sorry, didn't know that.
But thanks for the help!
