News Editor Tutorial won't save - Help!

It just won’t save the information. I didn’t change any of the files. Just, downloaded the zip file, unzipped, and uploaded to my server.

The tutorial:

Here is my file
http://www.on5ram.com/news_editor/

Any ideas why it won’t save? I’m pretty new to .php and xml.

Any help is appreciated.
