Suddenly WEBUI and SSH don't work on SSG-5

I was working on setting the manage IP address on this system when the WEBUI stopped working.

Now neither the WEBUI nor SSH are working - but they had been.

The SSG responds to pings at the right LAN/Trust interface address for bgroup0.

The SSG responds to console cable connections and the configuration looks fine.

I would very much like to get the WEBUI working again.

But how??

I have tried (I believe this was the command)

set interface bgroup0 manage web

But it had no affect.
