Solved PerWorldWarps and Essentials ./Nick died.

Hello, Friendly people of Bukkit! Recently, my server has had a little problem:
1) I use the plugin PerWorldWarps. For some reason, and this has only started recently: When typing /warp, I get the internal error stuff, and this into the console:

Code:

When having no permission, I still get the you need the permission pww.list to do that text.


2) For some reason, the Essentials /nick isn't working. Upon typing it; nothing will happen. When typing /enick however, it comes up with the help thing: /enick [player] <nickname|off>. When typing in /enick [nickname] it just says, Your nickname is now: ||Owner|| MinecraftKnightz, whatever I set my nick as.

B...b...ump @Binner_Done @Scorpionvssub , any ideas?

Bump

Hmm, progress... Just tested it on my local server and, apparently its the CONFIG of a plugin causing it... :/

EDIT by Moderator: merged posts, please use the edit button instead of double posting.
Sorry mod.
Progress, fixed war ps by deleting and recreating config, still no progress with nicknames.
Dang, for some reason /warp was disabled in the config. Now soved
