Please help me.

My website was working fine, but something happened and now I can't acess the pages.
if a dial, for example, http://www.teste.com/home i have a not found page.

Someone can help me?

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.

sounds like an htaccess problem. Do you have an htaccess file, and what happens if you remove it? Also, you mention that it was working before you added the subdomain, what happens if you restore to your backup?
