Server log is a start, but for an issue as general as this, we really need to know about your environment.

 

Windows 7.

I posted my log.
I don't know what to try.

 

Bukkit's out of date

 

I tried updating it, then I got an older version.
Edit: I got an older version because it started happening when I got that version.

I think it may have been CommandBin, because it works now :/

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

You are op'ed, correct? because you don't have a permissions plugin that i see.
