Hi, I'm trying to move a project from Zope 2.3.2 to Zope 2.4.0. Once I move to 2.4.0, I get lots of the following errors on startup: 2001-08-06T11:32:26 ERROR(200) Zope Couldn't install Membership Traceback (innermost last): File /usr/local/zope/2.4.0_base/lib/python/OFS/Application.py, line 713, in install_product (Object: ApplicationDefaultPermissions) (Info: Membership) File /usr/local/zope/2.4.0_base/lib/python/ZODB/Transaction.py, line 302, in commit File /usr/local/zope/2.4.0_base/lib/python/ZODB/Connection.py, line 420, in commit (Info: (('App.Product', 'Product'), '\x00\x00\x00\x00\x00\x85\x0e\xb5', '')) File /usr/local/zope/2.4.0_base/lib/python/ZODB/FileStorage.py, line 663, in store (Object: dev/var/Data.fs) ConflictError: ('\x00\x00\x00\x00\x00\x00\x00\x00', '\x03>9\xad\xbf;\xcbD') The complete list of these errors, in order, is: LoginManager Membership PlugIns PythonScripts StandardCacheManagers ZPatterns ...they all report the same identical ConflictError, including the OID-y bits. I'd love to know what's going on here but I'm completely stumped... cheers, Chris
