In reference to the ticket made on: #6
I see you say just go into the plugin.yml but I don't see a file named that, all I see is one named config.yml. I am running Snapshot 5.170.0 VoxelSniper if that helps any, I just want to get it back up and running asap for both as I love your plugin but also we heavily rely on party chat

When you open the .jar (if you're over FTP or SSH, download it to your machine first and use something like WinRar or 7zip), in the root folder you should see "plugin.yml". Open that, and on line 38, you should see "p:", change that to "performer:". Save and reupload the .jar to the server and restart it - that should do it.

If it doesn't: /p is also aliased to /party - if possible; you could use that - and if you really need the /p command, you could alias it to /party with http://wiki.bukkit.org/Bukkit.yml#aliases

In continuing from ayyy's comment, configuring an alias in the http://wiki.bukkit.org/Commands.yml (command aliases were recommended to be moved there from the bukkit.yml some time ago) rather than editing the plugin.yml is the 'correct' way of doing this, and is quite a bit more flexible and future proof.
