I was away from home for a week, and on the first day of my absence I noticed that my web server wasn't running for some reason... several of you sent me emails when you found the same problem, thank you very much for that. Unfortunately I couldn't do anything about the problem before my return (note to self: find time to get that remote administration thing working again...), but at least now everything should be back to normal. My apologies for any inconveniences...
