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): File /home/zope/Zope-2.5.1/lib/python/ZPublisher/Publish.py, line 150, in publish_module File /home/zope/Zope-2.5.1/lib/python/ZPublisher/Publish.py, line 114, in publish File /home/zope/Zope-2.5.1/lib/python/Zope/__init__.py, line 159, in zpublisher_exception_hook (Object: Zope) File /home/zope/Zope-2.5.1/lib/python/ZPublisher/Publish.py, line 89, in publish File /home/zope/Zope-2.5.1/lib/python/ZPublisher/BaseRequest.py, line 278, in traverse File /home/zope/Zope-2.5.1/lib/python/OFS/Application.py, line 102, in __bobo_traverse__ (Object: Zope) File /home/zope/Zope-2.5.1/lib/python/ZPublisher/HTTPResponse.py, line 492, in notFoundError NotFound: (see above) What can I do to get my server back into working order?
