I tried downloading a directory folder using wget, and it seems to have worked properly. However all the PHP files are empty. I know that they should not be empty as they show a file size on the web directory.
The folder I am trying to download is here:

I used these directions to download recursively with wget.
Any ideas on why they are downloading blank/empty?
