[Zope] AttributeError: _v_blocks

[Chris McDonough]

Try setting all of your Zope files' and directories' permissions to 770
or similar, and make sure you're running under a user who has write
access to the Zope tree.  This is likely a permissions problem.  When
you run it as root it switches to the "nobody" user, and its likely the
nobody user cannot read or write to something it needs.
