Hi EveryOne, We recently upgraded zope on our server from 2.5.x to 2.6.x, after upgradation one of the products started giving an Import Error for module iClass. This error is coming from a folder. There are no ZClasses defined in the product, hence usual solution of emptying the subobjects tab is not feasible here (atleast I think so). The name of the product is Volunteer product. What this product does is,it allows users to register with a web site. For every user a folder is created the information that user enters while registering with the website is stored as properties of his folder. All these member folders are stored in a seperate folder called "Members". It's this "Members" Folder that is giving the Import Error. Also some of the folders inside "Members" folder are giving an error saying doc string of the object is empty etc. All the folders are ordinary folders which are added using the "manage_addFolder" function We managed to restore the website by switching back to Zope 2.5.x but don't want to stay with it for long. Awaiting your response. Thanks in Advance Shashank Ashtikar
