It's been months since the plugin broke and nothing was really done to try to get it working again. I've done some tinkering with dynmap on my own test server to see if I could get it to show up, and got it working.
The problem was that I guess it may have just been a bit overwhelming to get working properly since no one really knew how it worked apart from Lynxy who set it up the first time. Now I know a bit how it works, and managed to fix it up and get it working this time.
So, apologies for all the long months of it being broken.
It's going to be a bit slow for now, as it's doing rendering stuffs, but sooner or later it will be back to normal.
