After setting cookiepath I can't log in with FF

[Eagle Creek]

Howdy!

I have 2 forums:

domain.nl/forum and domain.nl/testforum

Because the cookies where biting each other I changed the following things.

On forum I changed Path to Save Cookies to "/forum/" and on testforum I changed Path to Save Cookies to "/testforum/.

But; very strange. I can log in with IE and FF (internet explorer and firefox) and just browse, post and nothing happens. But when I try to enter my Admin Control Panel using FireFox I get "you are now logged in Eagle Creek" and then I'm back at the login page!
When I use IE I can just log in.

My moderators have the same problem using the modpanel.

Run this script to fix this:

And then leave your cookie domain and path at the default settings. There is no reason to change these. If you need to specify a unique cookie, use the cookie prefix setting in config.php instead.

There is no reason to change it? Both forums are running on the same server. When I log in on .nl/forum I get logged off are the testforum.

Is that normal?

:$ I'm sorry..

I will do that I guess. But why's that option? I guess I don't understand the use of it then.
