Re: One more 'Headers Already Sent' error. :-(

Well, I have traced this down to line 4 in the following code 'include("header.html");' which just includes my navigation bar. If I comment it out, everything works great, if I leave it in, I get the error Headers Already Sent. The file it purely html. What could be the problem?? Thanks in advance! <?php error_reporting(2039); include("dblib.inc"); include("userlib.inc"); include("header.html"); $message=""; if ( isset( $actionflag ) && $actionflag == "login" ) { if ( empty( $form[login] ) || empty( $form[password] ) ) $message .= "You must fill in all fields<br>\n"; if ( ! ( $row_array = checkPass( $form[login], $form[password] ) ) ) $message .= "Incorrect password. Please try again<br>\n"; if ( $message == "" ) // we found no errors { LastLogin($row_array[login]); cleanSession( $row_array[id], $row_array[login], $row_array[password] ); header( "Location: index.php?".SID ); } } ?> "Brad Melendy" <brad@techknow.biz> wrote in message news:20020625200359.74200.qmail@pb1.pair.com... > Hi All, > I know this has come up before and I've read some posts so far, but this is > still eluding me. > > I have come to understand that typically, if you are getting an error > message about your headers having already been sent to the browser, you are > writing bad code.
