I think that when I dial http://www.teste.com/home, for example, php looks for the home directory in my domanin. I have many subdomains, one of them is forum. If I dial http://www.teste.com/forum, it loads the forum directory.

In other words, php is not looking for a class but a directory. And I don't know how to figure out this problem. I'm not sure, but before I add the subdomains, It was working fine.
