I've received reports that DD is not responding properly on a number of occasions, with people seeing 404 errors, Internal Server Errors and occasionally a white screen that says simply 'test'.
I've been unable to reproduce these things here – that's not to say they don't exist, just that the conditions are not right for me to see it. If you experience such an error, please forward to me the exact address you've seen this at (copy and paste it from your address bar) so I can see if there's some kind of pattern going on, or try to make it happen myself.
I can only assume it's something to do with the modifications I made the other day, but I can't see why as yet.
Please bear with me while I try to look at what's going on, and please provide me as much information you can in an error report.
