All my functions are repeated. And other thing, I do login on my forum. And before that I go to other my forum and I do the login, when I go to my other forum is not login.
Functions are repeated...?? Going to have to go into a bit more detail on that.
Are both these forums on the same domain?? Can you post the URLs??
They're not functions, they're settings. Have you added any plugins yet??
On
http://www.forum-pt.com set the cookie prefix to 'main' or something, clear your browser cookies, login again, then the cookies on the two forums should be separated.
No, don't do that, because then it'll only work if you have www. in the URL when you visit the forum. Your settings are fine for that forum. If they don't work for you, clear your browser cookies, try again.
I Have already do that and is not working ;C
What plugins do you have installed?
