Session data lost between redirects

Just an idea... do you redirect to another directory?

If so the probem may lie in you cookie settings in config.php. You may have the cookie locked to a certain directory so when you redirect to a different one the cookie is not sent thus having no session data.

config.php

Code:

$config['cookie_domain']    = '.example.com';
$config['cookie_path']        = '/';

Make sure you have a trailing forward slash for cookie path and a fullstop in front of the domain.
