The trouble is in your first line:

// index.php
<?php
session_start();
ob_start();
?>

You use php comment outside of <?php ?> block so it is not treated as php code but as html code. That means that you send html before calling session_start() and ob_start() which is incorrect since both functions have to be started before ANY output is sent. Simply remove the first line or put it within a <?php ?> block.

<?php
// index.php
session_start();
ob_start();
?>

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at C:\xampp\htdocs\trail\index.php:1) in C:\xampp\htdocs\trail\index.php on line 2

It means you already send your header 2 times meaning this session_start();.

It should be only 1 session_start();.

It has nothing to do with the CSS file.

I'm not sure why you post it.

OK. There are two things that vome to my mind:

there is some outbut (mybe a space or newline) before session_start(). Make sure session_start() on the very top of the script and nothing else is before it.
your php.ini has session.cache_limiter set up incorrectly, try setting it to:

session.cache_limiter = public

(found this on google, not sure if it solves the problem of yours)

reg warning plz help me.... thanks in advance
