Druid rez greyed out in action bar

[Maddocks]

I just started using nUI and in bear form i put my rebirth on my action bar but it is completely greyed out .. and faded so much i can't even see it.. so i cant seem to click on it in bear form or combat to rez someone. Can any one help me on this?? I really like this UI but i really need to use that fast in raids.

thanks

Have you checked to see if it changes when in caster form ? It might be that either nUI or Blizz have made it so that spells grey out when not usable.

If it does work differently with the change in form try it without nUI and see if it is any different. In which case it may be an nUI change to grey out usability but I did think the usability tests nUI does used Blizz's own tests.
