Chrome users can't stay logged

[Divvy]

Hello guys,

I need your help here...
Some of my users, most of them, using chrome, can't stay logged in my forum.
They login and after some few minutes in the forum, they are logout, even if they choose "remember me".

Can someone please help me?
I am using Firefox and I dont have any problems.
But I tried using Chrome and same issue happened to me.

My config is set as default options.
My cookies configuration: http://i.imgur.com/q21ASXq.png

How can I fix this problem?

Note: I have this set to YES:
AdminCP > Settings > Options > Cookies and HTTP Header Options
Add No-Cache HTTP Headers

Because I had some login problems:

"First I thought that it won't let me log in. I try to log in with my admin username and password, but it returns the non-logged-in homepage again. But I did a refresh and I was logged after all.
Than, when I read new posts doesn't mark as read, I always need to refresh page to update posts status."

That solved my problem... but now Im having this Chrome issue with the login...

Help

Thanks,
Tim
