Header Error

[Meekos]

I am receiving this error when I try to redirect to another page in my web site.

Cannot modify header information - headers already sent by

I've identify that the problem is with this code.
if (!isset($_SESSION['admin']) || $_SESSION['admin'] != true) {
header ("Location:

http://".$_SERVER

['HTTP_HOST']."/login.php?category=a");
exit;
}

Can anyone tell me if I am missing something here?

Somewhere, you are creating HTML output. Either by having text (even whitespace) outside of your <?php ?> or inside it with a print or echo.

Thanks for the advice. I had an echo at the very top of my code. I did a search for header errors before posting. None of them worked.

Thanks for this link it was very informative.
