I am developing a simple php website named : http://www.dopanchat.com

I don't know if it's server problem or anything else.

Extending your session timeout is an approach but I won't recommend to expand it too much :)

Instead your application could detect user activities and refresh the session expiry time accordingly.

After all it doesn't really matter what is the session's timeout at some point user will lose the authentication due to the expired session.

Basically the expiry count down always starts after user's last action and not from the moment s/he logged in to your system.
