session is being expired autometically

Hello Guys,

One of my codeigniter Application is not working properly on the server but it's working on my localhost and also working on another VPS server. But not working on my cPanel hosting.

I use wordpress and codeigniter mostly and this session issue is causing only with codeigniter not with wordpress.

I'm using autoload to load session and all others.

Let me know if you guys need any other information

Thanks in advanced.
