Hi there, I created a 4.1a3 buildout and added all needed products, of which I had to adapt some to be able to start at all. Then I copied the data.fs of a 3.5x site. Now in the ZMI, when I want to navigate to the plone 3.5 folder I get the following error: What can I do to fix that? Do I have to prepare the Data.fs somehow? thanks robert 2011-03-02 11:57:55 ERROR Zope.SiteErrorLog 1299063475.730.425785426825 http://localhost:8481/focus/focus Traceback (innermost last): Module ZPublisher.Publish, line 115, in publish Module ZPublisher.BaseRequest, line 437, in traverse Module ZPublisher.BeforeTraverse, line 97, in __call__ Module Products.CMFCore.PortalObject, line 78, in __before_publishing_traverse__ Module zope.event, line 23, in notify Module zope.component.event, line 24, in dispatch Module zope.component._api, line 136, in subscribers Module zope.component.registry, line 321, in subscribers Module zope.interface.adapter, line 585, in subscribers Module zope.component.event, line 32, in objectEventNotify Module zope.component._api, line 136, in subscribers Module zope.component.registry, line 321, in subscribers Module zope.interface.adapter, line 585, in subscribers Module plone.browserlayer.layer, line 14, in mark_layer Module zope.component._api, line 179, in getAllUtilitiesRegisteredFor Module zope.component.registry, line 176, in getAllUtilitiesRegisteredFor Module ZODB.Connection, line 859, in setstate Module ZODB.Connection, line 913, in _setstate Module ZODB.serialize, line 613, in setGhostState Module zope.component.persistentregistry, line 40, in __setstate__ Module zope.interface.adapter, line 91, in _createLookup Module zope.interface.adapter, line 439, in __init__ Module zope.interface.adapter, line 476, in init_extendors Module zope.interface.adapter, line 480, in add_extendor AttributeError: type object 'IDatabaseSettings' has no attribute '__iro__' 2011-03-02 11:57:55 WARNING OFS.Uninstalled Could not import class 'IThemeSpecific' from module 'focus.theme.browser.interfaces' 2011-03-02 11:57:55 WARNING OFS.Uninstalled Could not import class 'IFocViewletManager' from module 'focus.theme.browser.interfaces' 2011-03-02 11:57:55 ERROR ZODB.Connection Couldn't load state for 0x19746b Traceback (most recent call last): File "/home/zope/focus4/eggs/ZODB3-3.10.1-py2.6-linux-i686.egg/ZODB/Connection.py", line 859, in setstate self._setstate(obj) File "/home/zope/focus4/eggs/ZODB3-3.10.1-py2.6-linux-i686.egg/ZODB/Connection.py", line 913, in _setstate self._reader.setGhostState(obj, p) File "/home/zope/focus4/eggs/ZODB3-3.10.1-py2.6-linux-i686.egg/ZODB/serialize.py", line 613, in setGhostState obj.__setstate__(state) File "/home/zope/focus4/eggs/zope.component-3.10.0-py2.6.egg/zope/component/persistentregistry.py", line 40, in __setstate__ self._createLookup() File "/home/zope/focus4/eggs/zope.interface-3.6.1-py2.6-linux-i686.egg/zope/interface/adapter.py", line 91, in _createLookup self._v_lookup = self.LookupClass(self) File "/home/zope/focus4/eggs/zope.interface-3.6.1-py2.6-linux-i686.egg/zope/interface/adapter.py", line 439, in __init__ self.init_extendors() File "/home/zope/focus4/eggs/zope.interface-3.6.1-py2.6-linux-i686.egg/zope/interface/adapter.py", line 476, in init_extendors self.add_extendor(p) File "/home/zope/focus4/eggs/zope.interface-3.6.1-py2.6-linux-i686.egg/zope/interface/adapter.py", line 480, in add_extendor for i in provided.__iro__: AttributeError: type object 'IDatabaseSettings' has no attribute '__iro__'
