No, no directories have to be moved; what he is saying is that you need to make sure that you have entered the proper paths in places where you use them.
In his case, he needed to use ".." in place of "." in his forum's index.php to reference the scripts properly.
I'm not sure which scripts you are talking about - are you saying that your forums index.php is blank, too? We need a little more info about what is wrong and what you changed/did.
