Header() problem

[andor1995]

Hey, I'm working on a website and on my pc it works fine, but on my host it keeps giving me errors.

Error:

Code: Select all

Warning: Cannot modify header information - headers already sent by /code]

Code:
[code]if(isset($_COOKIE['username'])):
else:
header ("location:login.php");
endif;
$user = $_COOKIE['username'];

[egami]

header("Location: page.php");

case.. case is important.

Changed it, but it's still not working.

new code:

Code: Select all

if(isset($_COOKIE['username'])):
else:
header ("Location:login.php");
endif;
$user = $_COOKIE['username'];

are you sure this the only snippet of code all the code is needed to verify the source of the problem.
