I'm getting this traceback:
======================================================================================

================================================================================================

Though everything seems "to me" to be okay.  This was originally a
grokproject based application and uses grok 1.0a3 but I have been
incrementally/painfully changing the versions of components to get it to
run with ZODB3.9.0b1  

The server starts but when I try to access http://localhost:8080 I get
the above error.

The principal in site.zcml looks like this:

      <principal id="zope.manager"
                 title="Manager"
                 login="admin"

password="17e15cddd033e22ae348aeb5660fc2140aec35850c4da997"
                 description="OSHIP Developer"
                 password_manager="SHA1"
                 />


Any ideas where to start on this?

Thanks,
Tim
