I am trying to upgrade my zope to see the new features in 2.3.0 a2 (from 2.2.4). I installed, copied my previous /var /Extensions start stop and access files and then started up zope. All works well *except* the few zClasses that I had written now do not work. They have survived previous upgrades. Can anyone point me in the right direction? I am unclear how to debug this as there are no apparent error messages. Thanks, John -- .................................................................... .
