The line
header('Location: '.$_SERVER['HTTP_REFERER']);
is trying to set the header information AFTER
/home/songc1/public_html/guestmap/badwords.php:36
has already set the header information, by:
(a) issuing a print or echo statement
or
(b) containing some white space that the browser is rendering as output

The more common problem is (b)

Best way to check is to call badwords.php directly into a browser, and see
if you get any (even blank) output rather than a "document contains no
data" message.
