1,2 update Help?

Here is why. you run a bukkit server BUT bukkit hasnt released bukkit 1.2. yet. but they have got a developemnet release (stable).

Here is a link: http://dl.bukkit.org/downloads/craftbuk ... atest-dev/

You will have to delete you Craftbukkit.jar file on you server.

Then re-name the Craftbukkit you downloaded from link above to CraftBukkit.jar

Then upload the NEW craftbukkit.jar file onto your server. It should work now

If not pm me

You need to explain better what your problem is.
Are you using craftbukkit?
Are you using a vanilla server starter?
What plugins do you have?
