You've got at least two line breaks being sent as output before your call to session_start(). Remove them.

EDIT: Also try posting your own problem in a new thread next time, rather than hijacking someone else's.

okay i dont get what you mean by the line break. i have removed all the spaces. sorry next time i will post on on a new wall

bradgrafelman

You've got one line break here:

<?php virtual('/pro/Connections/feedback.php'); ?><!-- LINE BREAK HERE -->
<?php

and another one here:

$totalRows_Recordset1 = mysql_num_rows($Recordset1);
?><!-- LINE BREAK HERE -->
<?php
// *** Validate request to login to this site.
if (!isset($_SESSION)) {
  session_start();

(Note I added "" HTML comments in the above code for visual clarification.)

Anything outside of <?php ... ?> tags gets sent directly as output. Either remove the line breaks, or, even better, remove the unnecessary closing (and subsequent opening) PHP tags.
