Dear Zope users, when I try to access the Zope top/root "Security" tab but (and only with this Security tab), the following error occurs: Traceback (innermost last): File /opt/zope/lib/python/ZPublisher/Publish.py, line 214, in publish_module File /opt/zope/lib/python/ZPublisher/Publish.py, line 179, in publish File /opt/zope/lib/python/Zope/__init__.py, line 202, in zpublisher_exception_hook (Object: ApplicationDefaultPermissions) File /opt/zope/lib/python/ZPublisher/Publish.py, line 165, in publish File /opt/zope/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: manage_access) File /opt/zope/lib/python/ZPublisher/Publish.py, line 102, in call_object (Object: manage_access) File /opt/zope/lib/python/AccessControl/Role.py, line 231, in manage_access (Object: ApplicationDefaultPermissions) File /opt/zope/lib/python/App/special_dtml.py, line 120, in __call__ (Object: access) (Info: /opt/zope/lib/python/AccessControl/access.dtml) File /opt/zope/lib/python/DocumentTemplate/DT_String.py, line 502, in __call__ (Object: access) File /opt/zope/lib/python/DocumentTemplate/DT_With.py, line 148, in render (Object: _.namespace(valid_roles=valid_roles())) File /opt/zope/lib/python/DocumentTemplate/DT_In.py, line 630, in renderwob (Object: permission_settings) File /opt/zope/lib/python/AccessControl/Role.py, line 166, in permission_settings (Object: ApplicationDefaultPermissions) File /opt/zope/lib/python/AccessControl/Role.py, line 161, in <lambda> TypeError: (see above) ------- So far, I used Zope luckily, especially the Portal, but these days I tried to work some more on it and maybe added a product or tried to alter some security options, but I can't attribute the occurrence of this error to one specific thing I did. Could You help, please, how to find out what to do and how to re-establish this folder? THANKS!
