Duplicate Session IDs? !

Hi -

I am getting the same error message, ie. "Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at /home/content/M/a/d/Madison1Forms/html/employee/Picnic_2008/index.php:1) in /home/content/M/a/d/Madison1Forms/html/WA_SecurityAssist/Helper_PHP.php on line 5"

and I've googled it and it says to make sure session start command is at the top, and it is. At least, this is what's at the top right now:

<?php require_once( "../../WA_SecurityAssist/Helper_PHP.php" ); ?>
And in that page - this is what is at the top of it:
<?php require_once( "HelperGroupsRulesPHP.php" ); ?>
<?php require_once( "Mail_PHP.php" ); ?>
<?php
if (!isset($_SESSION)) {
session_start();
}

And I've tried moveing these lines: <?php
if (!isset($_SESSION)) {
session_start();
}

above the others and it doesn't help.

Also - I'm not sure why but when using Security Assist - it shows all these pages (in the pages access manager thing) as needing to be a "USER" security - but not all of them have the php functions on top like (what I described above) - so some of those pages don't error out, and I thought I would be able to compare them to see where they're different, and it's because they don't have any user restrictions whatsoever - so of course theres no error message on some of them because there's no code to screw them up. I know this is confusing. So the first problem is that header error message on some of my pages and the other problem is that security assist is showing some pages that require the user to be a "registered USER" but it's not adding the necessary code - and no, they weren't open when I assigned it.

Thanks!

  Add the session_start line to the top of the page, but add the rest below. That should prevent the error. You may also have to move the setcookie IF statement to the top.
