Code:
A PHP Error was encountered

Severity: Warning

Message: Cannot modify header information - headers already sent by (output started at C:\xampp\htdocs\classic\system\libraries\Exceptions.php:164)

Filename: libraries/Session.php

Line Number: 662

in server it runs fine. no session warning.

Well, warning above still means you are echo-ing something / somewhere.

Reason that on your production you do _not_ see this error, is because most of production system supress (do not show) warning and information messages, only errors;

So, look you code once more and check where you are sending output to browser.

Cheers,
Smilie

In your PHP code do not include the ending php tag ?> only in your html documents do you need it.

Make sure your files are not saved with the BOM also.
