Login Problem

I dont know what to state on this problem encountered. This is the scenario, i can successfully login on my website but after clicking the forum or any links i need to login again just to use other feature of the website. How could i resolve this problem. thank you

It appears that cookies are not sticking. I actually suffered this very problem when using an installation that was located in the sub-directory of another installation. The funny thing is, when I logged into one web site, I also logged into the other one.

so how you have resolved this problem. is there any way to solve it immediately.

I never figured out how to resolve the issue. Anyone care to weigh-in?
