When i login to my backend on MU i get the following messages:
Warning: Cannot modify header information - headers already sent by (output started at /home/content/s/t/a/startuplabnet/html/wp-admin/includes/mu.php:1) in /home/content/s/t/a/startuplabnet/html/wp-includes/functions.php on line 798

It does appear that everything is working fine, yet it's really annoying because if I add a new post or make any changes to plugins, etc i get this warning and i have to go back to the previous page. IS there a way to turn off these messages?????
