Crash report

Hi there,

I'm running a server and a ''friend'' of mine crashed the server... Is the server unfixable or do I still have a change? I have no plugins anymore but the server still keeps crashing.
This is what my crash report says:

Code:

I am by no means skilled enough to say why it crashed, but if nothing works, you can try deleting the block at "-1485,62,-651" (frosted_ice) using MCEdit or similar, as this is the block that causes the server to trip over. This is the solution provided here, with the exact same error. It was caused by the Frostwalker enchantment. If it works again, you could try running "/version" and see if your version is outdated.

EDIT: I think this belongs to Bukkit Help or so, but definitely not in "Plugin Deveolpment". So, for the next time consider posting it there.

 

@I Al Istannen
I understand what you are trying to say, but the thing is that I can't join the server anymore. When I start it, it runs but when it is ready the server stops. My question is if you can delete a certain block in your minecraft server when you can't join the server?

 

@JoPie
Google MCEdit. It allows you to modify the world without logging in to the server.
