I had this plugin working great, but it's recently given up the ghost - I think since WP3.0.1 or thereabouts. The counter displays, but won't count.
I initially suspected a js clash etc., so disabled all plugins, all custom functions, all js etc, still no go.
So then I set up a totally fresh wp install (completely untouched), and tried it out with TwentyTen, Classic, and Default. The box displays, the onkeydown and onkeyup are present in the code, but again, no counting.
Any advice would be very gratefully received! I really need to get this working.
