Multi User problem

I just downloaded a multi-user script from majorscripts.com that uses wordpress. I’ve got it installed and everything seems to be working but I’m having one problem I can’t seem to figure out. Whenever a new user is added the script is supposed to create a new directory with that users name so you would access it like this

https://mydomain.com/user/

Instead of creating a folder named “user” it is creating a file instead of a folder and the contents of the file read as follows:

<?php chdir(“../wp-admin/”); require_once(“.”); ?>

Does anyone know why this is doing this? And how do I get it to create a folder instead of a file. I realize the script that is doing this is probably not a wordpress script but rather part of the multi-user script from majorscripts but I was hoping someone else on here has used it. Here is an example of how it is supposed to work:
