I still have WebRep installed on my Fx, and it shows grey for me on your site, which means no votes or not enough votes to register anything. So it might be a problem with Avast!'s servers.

Can’t say for sure, though, since the WebRep I have installed is the Beta they released before it was ever bundled with Avast!, so it might not even be working correctly for me.

Anyone have a regular-release WebRep they can check this guys site with?
