I am also getting the following debug message PHP Warning: Cannot modify header information - headers already sent by (output started at /home/content/whatever/xxxxxxx/adminsection/includes/keepalive_module.php:34) in /home/content/whatever/functions/general.php on line 21
Can't seem to replicate this on my own site.

What's different in your admin files compared to a fresh brand new uncustomized install of ZC?
