Session Flashdata not work in Chrome

[eluser]edidiway[/eluser]
Hello, can anyone help me to figure out why Session Flash Data does not work properly in Chrome ?

I have code like this :

Code:

$admin['redirectLink'] = $this->session->flashdata(WEB_TITLE."_current_link");

$admin['redirectLink'] will have the value in Firefox, but when I used Chrome, sometimes the value was empty and sometimes the value was not empty.
I dont know where is the problem.

Your help was very appreciated..
