BrowserPlus.init Error

My problem:
I've been getting the following error:

bpPlugin.unapprovedDomain: undefined

I can't find any information on what this error means.

My situation:
I've uploaded the File Zipper example to a hosting site; the call to BrowserPlus.init() looks pretty straightforward. I'm using Firefox 3.0.11. I've got BrowserPlus 2.3.1. My page loads up just fine on IE, though (when on the hosting site). When I host it locally (through Visual Studio), my page works with both Firefox and IE. Further, I the File Zipper example straight from the BrowserPlus site works too.

Any idea what could be causing this error when I try to load my page from the hosting site with Firefox?
