Dear all, Zope 2.5.1 running on Win2K server. Recently we found that: a) Users in the root acl_users folder cannot now login. However I can get in on the 'superuser' Zopeadmin ID no problem. b) Whilst the user list exists and is visible, clicking on a user e.g. xxxxx which then invokes: http://url/acl_users/manage_users?name=xxxxx&submit=Edit Fails with a Zope generated error page: Zope has encountered an error while publishing this resource. Error Type: AttributeError Error Value: name - - - The same thing also happens if I generate new other 'acl_users' folders in sub-trees. I can populate them but not then edit them. Recent changes to the site are: i) HTTP Port changed from 8080 to 80; ii) ExternalEditor product loaded Assistance on where I go from here would be greatly appreciated.
