   Hi all,

   I've been trying to force anybody in the admin panel to logout. :) Actually I want to use this for a different purpose(security) but for the basic, I'd need to get through this step.

   I expected the following code does the job but it doesn't.

   function force_logout () {
wp_clearcookie();
do_action('wp_logout');
nocache_headers();
$redirect_to = 'wp-login.php';
wp_redirect($redirect_to);
exit();
}
add_action ('admin_head', 'force_logout');

   Does anybody know the solution for this?

   Ok,

   If I embed the following code at the very beggining of the wp-admin/admin-header.php it works.

   header( 'Location: ' . get_settings('siteurl') );
exit();

   However, if I do this as a plugin,

   /*
   Plugin Name: Go Home
   Plugin URI:
   Description: forces anybody to go home
   Version: 0.1beta
   Author: Goxu
   Author URI:
   */

   function force_gohome() {
   header( 'Location: ' . get_settings('siteurl') );
   exit();
   }

   add_action ('admin_header', 'force_gohome' ,1);`

   The priority is set to 1, so I assume that the funciton will be loaded prior to anyother funciotns. Am I correct?

   If so, why doesn't it work? Any information will be greatly appreciated.

   I haven't been able to figure out yet.

   There was a minor mistake in the last line. the 'admin_header' had to be 'admin_head'.

   Still, I keep getting the following error in the admin panel after enabling this plugin. Is it only me getting this or do you also get this error too?

   Warning: Cannot modify header information - headers already sent by (output started at /home/wordpress/wp-admin/admin-header.php:16) in /home/wordpress/wp-content/plugins/force_gohome.php on line 12

   <?
/*
Plugin Name: Go Home
Plugin URI: http://example.com
Description: forces anybody to go home
Version: 0.1beta
Author: Goxu
Author URI: http://example.com
*/
function force_gohome(){
header('Location: ' . get_settings('siteurl'));
exit();
}
add_action('admin_head', 'force_gohome', 1);
?>

   The 'init' hook did the job.
