Ok, I'll search my message in the newsgroup and include it.

Sorry for that, I thought you had a backup.

Who me? I think it's a responsibility of each administrator to do a
backup before doing a software upgrade.

Anyway, now I just remmember that somebody disscussed just some days
ago a way of correcting mistakes if you have already upgrade your zope. He
said that you had to export as XML, look for a string (If I'm not bad it was
something like <object>, you've to look the archives) erased it and reimport
the object again.
