The couldn't load state errors are probably from a product not getting initialized properly. If you set up your STUPID_LOG_FILE environment variable and point it at a file before starting Zope (if you haven't already), you may be able to see a failed product init before the state errors, which would give you a clue. That said, from your description, it's probably kmnetnews that's not getting inited properly. I haven't seen Kevin Dangoor around lately, I wonder if he's still maintaining it. "Bak @ kedai" wrote:

hello all

there are also tracebacks "Couldn't load state" when starting zope in debug mode..

platform RH6.2, straight ZServer products - KMnetnews, a few ZClasses,
