Hi Steve, I've got an app using ZPatterns "ZPatterns-stevea-20010204" I'm currently getting a lots of barfage (see ps) when trying to upgrade to Zope 2.4.0. What should I do? cheers, Chris PS: 2001-07-27T14:05:58 ERROR(200) Zope Could not import Products.DataSkinAddons Traceback (innermost last): File /usr/local/zope/2.4.0_base/lib/python/OFS/Application.py, line 552, in import_product File /stuff/AlexCons/Products/DataSkinAddons/__init__.py, line 1, in ?
