My members have to keep re logging in after every 5 minutes

This is what one of my members posted

you have to constantly log in and log in and log in? After every other refresh, this site requires you to log in again. It's most annoying. You start to create a thread or response and when you try to submit it, it makes you log in again. Does it do this for everyone, site admins included? Is it only me? Is it simply an oversight in the options for the setup of the forum software ("force login after 3 minutes")?

How do I fix it?
