That is very weird. Did you use the Builder to create the JAR? If so which one (Stable or Dev) or did you download it from BukkitDev or SourceForge

ethan476 commented 11 years ago

I tried builder and craft bukkit, I'm using linux CentOS

keir-nellyer commented 11 years ago

Can you send me your CommandsEX jar file please?

JamesNorris commented 11 years ago

This looks like a problem with outdated versions...

keir-nellyer commented 11 years ago

@JamesNorris I don't think it is, looks like the version in plugin.yml is 51.0. That's why I'd like to see his jar file.

JamesNorris commented 11 years ago

@iKeirNez May be, but then why would he change it inside the jar to version 51.0? And why wouldn't it load that? It should load any version you change it to.

keir-nellyer commented 11 years ago

@JamesNorris I have no idea, we can't tell without the jar.
