I just checked out what your vent server is responding with, and apparently, your vent server doesn't allow retrieving the vent info from.
For example, my guild's vent server responds with something like

Clearly a lot of information. But when your site responds to the query, it returns only:

Which means that your server is restricting status response. I'm not familiar with setting up the nuances of vent, so I'm not sure what you'd need to ask your host, but it looks like your host isn't very supportive of a status script (The code on my side actually uses the official ventrilo_status program that comes with the server software, so at the very least, I'm fairly confident the problem isn't on my side).
I'd ask your host if there's something special that needs to happen to get the vent status remotely.
