put ob_flush() this at the end instead of ob_end_flush()

maybe your include file (../admin/includes/connect.php) is printing a space or something?

I always double check that you don't have a space behind the php open and close tags in the include files

Put ob_start(); above session_start();.
Also put ob_clean above header("location: ../account.php?id=$id");.
