[Zope] Strange error when accessing Zope

[Konrad Hinsen]

After some pause, I wanted to work on my little Zope project again.
In the meantime, two things have happened to the machine on which
the server is running:
1) The IP address was changed.
2) The machine was rebooted.

When I now try to start the Zope server, everything looks fine, but
when I then try to access any page, the result is:


          Site Error

          An error was encountered while publishing this resource. 

          Resource not found

          Sorry, the requested resource does not exist.

          Check the URL and try again.

          Resource: manager GET

with the following traceback information:

Traceback (innermost last):

What can I do to get my server back into working order?

Konrad.
