There is no need for any of that info.

RumbleIV
Your issue is;

1)Update the plugin to the newest version
2)Double check that the sever is using Java7, and not Java6 for some reason

 

Plugins are not always friendly to eachother. The build is gonna decide a lot.

 

I have java 7 but how do i check if the server is using java7?

I would have said the same thing.

PLEASE provide us this info. *with a smile*

It's all on this page. http://dev.bukkit.org/server-mods/rankuponkills/#comments

 

Something's obviously wrong; "51.0."
Do you have the dependency "Vault?"

 

Darky1126 -_-
RumbleIV your java version is outdated, so you cant run the plugin. my guess is that server still uses java 6, try check for older java installs on the computer (if windows, use "programs and features" on control panel)

 

necrodoom Actually, in the server.log, it says nothing about Vault, and on the BukkitDev page, it says "Dependencies: Vault."

 

the error complains about java version, not unknown dependency vault.

 

Might as well kill two birds with one stone.

Sec... Lemme test something in my jar (I recommend watching for a notification.)

RumbleIV -- I'd go to your programs and features, search "Java"


Notably, I have 4 installed. If you don't see Java 7 Update 7 on yours, you have the wrong Java. If you have any older versions of Java, I recommend uninstalling them, as they have security flaws. (That's why I assume major versions are pushed.)

the issue I had was I had to download the plugin mcore and the problem is no longer an issue. it also needs Vault like Jade has said. hope this helps
