Well, I was a noob today and I decided to use the new bukkit dev build for my server. When I did it, stuff wouldn't work like MOTD or factions. So, I changed back to 1.5.2 and it said internal server error. After I learned the problem I didn't realize I should have backed it up. I will have to wait for Beta build to put my server back up now, but I saw some servers with 1.6.1 working fine. What did they do differently to make it work?
Hey I run a decent server, I had the same problem! Heres the solution for "Factions"(MassiveCraft), First get the latest version of Factions than get mcore. Stop your server, move the files to the plugin's folder & restart your server. After this you should be good to go! ~Dearly, Hylax. Hope it works goodluck! Lol, Not sure about MOTD maybe an error. But factions should work.
