Hi, Actually this warning message is pretty poor. I’ve updated the sources with this new message: "Could not find a QueryExecutor with hint [{}] which is the hint for the storage engine, defined in your XWiki configuration under the [xwiki.store.main.hint] property. The default QueryExecutor will be used instead. Reason: [Can't find descriptor for the component [role = [interface org.xwiki.query.QueryExecutor] hint = [hibernate]]]" I hope it makes it slighty easier to understand… ;) So it seems we have a bug in our code. To work around it and till we fix it, I’d suggest you comment out the “xwiki.store.main.hint” property in your xwiki.cfg file and it should work fine.
