Do not echo $query or any output before session_start(); or
session_register("xxx"); (mean headers)
//echo $query
Or may be you can put ob_start(); before first output and put
ob_end_flush(); after last headers
ob_start();
echo $query
.
.
//your code.
.
.
session_register("ses_level");
ob_end_flush();
Hope this helps!
