session

[networkthis]

I noticed that you had echo $_SESSION['username'];

 

shouldn't it be $_SESSION['username'];

To show your settings, use a phpinfo(); statement in a .php file. There is a section in the output with the session settings. Copy and past that here so that someone can see what all the settings are.

 

If no error was displayed, that would mean that there is not a header/content problem.

 

There still are several possibilities, either with the session cookie or if your site is using the transparent sid on the url, as those are not automatically appended when you redirect...

sorry, I noticed I mean I noticed you had

 

<?php 

$_session['username'];

?>

 

shouldn't it be

 

<?php

$_SESSION['username'];

?>  

 

Why not just try to simply echo

 

<?php 
session_start();
echo $_SESSION['username'];
?>
