Hi,

This is a WordPress 2.1.1 problem.

I have already read How do I solve the Headers already sent warning problem? and attempted that solution.

I am trying to detect these URLs (permalink?c=feed) to set a cookie, and redirect to permalink.

But I get an error saying headers already set by wp-include/link-template.php:3.

PHP Code:

if ($_GET['c'] == "feed") {
$permal = the_permalink();
setcookie("feed", "read", time()+5400);
header("HTTP/1.1 301 Moved Permanently");
header("Location: $permal");
die; } 


That happens a lot. To fix this you should get this code before the code setting the header. Just try to set it before the whole template file.
