"Unknown server tag" when deploying website

[Paul]

Hi all,

I'm trying to deploy a small website that has a couple of custom
controls. This works fine locally, but falls over with an "Unknown
server tag" error when trying to parse the custom control reference in
the live/deployed site.

All of the binaries are in the "bin" directory. I have the tag prefix
registered in web.config.

Am I missing anything here?

Any help would be appreciated.

Thanks,

Paul
