Hi; I'm *still* having problems ridding myself of a product that somehow has etched its memory into Data.fs. The error I run into states Zope can't import module PTKDemo. I moved out all products that weren't essential, deleted them out of the ZMI and restarted Zope, but the error remained. Here's a traceback: Traceback (innermost last): File /apache/ZopeInstallation/Zope_software_home/lib/python/ZPublisher/Publish.py, line 223, in publish_module File /apache/ZopeInstallation/Zope_software_home/lib/python/ZPublisher/Publish.py, line 187, in publish File /apache/ZopeInstallation/Zope_software_home/lib/python/Zope/__init__.py, line 226, in zpublisher_exception_hook (Object: defaultRack) File /apache/ZopeInstallation/Zope_software_home/lib/python/ZPublisher/Publish.py, line 171, in publish File /apache/ZopeInstallation/Zope_software_home/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: manage_storageForm) File /apache/ZopeInstallation/Zope_software_home/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: manage_storageForm) File /apache/ZopeInstallation/Zope_software_home/lib/python/Shared/DC/Scripts/Bindings.py, line 324, in __call__ (Object: manage_storageForm) File /apache/ZopeInstallation/Zope_software_home/lib/python/Shared/DC/Scripts/Bindings.py, line 354, in _bindAndExec (Object: manage_storageForm) File /apache/ZopeInstallation/Zope_software_home/lib/python/App/special_dtml.py, line 244, in _exec (Object: manage_storageForm) File /apache/ZopeInstallation/Zope_software_home/lib/python/DocumentTemplate/DT_In.py, line 691, in renderwob (Object: manage_product_zclass_info) File /apache/ZopeInstallation/Zope_software_home/lib/python/Products/ZPatterns/DataManagers.py, line 104, in manage_product_zclass_info (Object: defaultRack) File /apache/ZopeInstallation/Zope_software_home/lib/python/Products/ZPatterns/DataManagers.py, line 92, in _unifiedZClassRegistry (Object: defaultRack) File /apache/ZopeInstallation/Zope_software_home/lib/python/Products/PlugIns/PlugIns.py, line 674, in unifiedZClassRegistry (Object: defaultRack) File /apache/ZopeInstallation/Zope_software_home/lib/python/Products/ZPatterns/DataManagers.py, line 86, in _zclassOK (Object: defaultRack) File /apache/ZopeInstallation/Zope_software_home/lib/python/ZODB/Connection.py, line 544, in setstate ImportError: (see above) Any ideas?
