is there an addon that rmeoves the spell is not ready yet, spam?

I think I have that addon before, it is named ErrorMonster but it don't remove only "The spell is not ready yet" it removes all any Error frame like Not enough mana or rage or energy or other. If that what you wanted.

The mod you want is called RogueSpam

You can configure which error messages you want to block and it will let everything else through.

just unclick error message or insufficient spell resources in combatlog (and audio settings.)

ErrorMonster is the best, you can tell it exactly what, and what not to show.
