Crontab is the daemon which runs cron jobs, and some distros have set up special files called cron.daily (or daily.cron I don't recall), cron.hourly, etc to make it easier to schedule jobs. As you're entering this through a control panel (presumably a web-based one?) I would guess that's not the problem. It could be that the hostings control panel software has had a hiccup? -- Thanks, Ash http://www.ashleysheridan.co.uk
