I had a similar problem a month ago with PTK and ZDiscussions and I consider this to be corruption of the ZODB not related to the particular products. You might be able to fix it by going into the DB directly through python; stop zope start python in zope/lib/python 'import Zope, ZServer; root = Zope.app(); dir(root)' and dig around from there I didn't know that trick at the time, so I fixed it by: exporting my objects from the root folder (fortunately, I'm virtual hosting and I only had to export a couple of folders) stopping zope replacing Data.fs with Data.fs.in starting zope importing my objects On Tue, 31 Oct 2000, Tony McDonald wrote: > Hi all, > I've been trying to install EventFolder into a Zope 2.2.1 system. > I've followed the instructions (I wouldn't be writing here if I > hadn't! :) and keep getting an error message; > > Error type: Could not load oid > ÷, pickled data in traceback info may contain clues > Error value: None > _______________________________________________ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )
