Nynox Web Site

I have set up 3 demo apps. They are deployed under webapps\www.nynox.com. I have not been checking lately. I tried to login a few days ago and those apps are no longer working. In "server.xml",

Host name="www.nynox.com" appBase="webapps/www.nynox.com" unpackWARs="true" autoDeploy="true"
xmlValidation="false" xmlNamespaceAware="false"
Host

above config string is to map http://www.nynox.com/nynoxdemo1/app/index.jsp. For some reasons, applications under webapps/www.nynox.com are no longer working.

I am investigating now.
