I believe that the directory you created "Beta" is outside of the root directory because everyone of your present site's addreses have "http://www.clinicforspecialchildren.org/CSC/" and then the page name.
I would check to see if the Beta file needs to be within the /CSC/ directory.
If I call: http://www.clinicforspecialchildren.org/CSC/Beta/, I get: "File Not Found
The requested URL was not found on this server."
When I should get:
You don't have permission to access /CSC/Beta/ on this server."
...if the file existed.
The same with: http://www.clinicforspecialchildren.org/Beta/, I should get:
You don't have permission to access /Beta/ on this server."
