clone of www.swoop.com
this clone is developed on CakePHP platform and I have a issues there.
I purchase that script from

password= password1

In that cms there is FCKEditor integrated and it is not working. It is
gives me that following error massage.

The requested URL /js/fckeditor/editor/fckeditor.html was not found on
this server.

Additionally, a 404 Not Found error was encountered while trying to
use an ErrorDocument to handle the request.

links are broken
