Hi there, I don't have any versions problems in a Grok 1.0. I get the zc.catalog 1.2. So it must be hurry.query! hurry.query is *not* locked down in versions.cfg. You should be using 0.9.2 or 0.9.3, *not* hurry.query 1.0. We need to think about how to prevent future occurrences of this issue. Regards, Martijn
