version 11.0.0 retail

The addon dont show dragonriding vigor charges anymore just if I reload the game in a dragonriding mount

Do you have the encounter bar visible?

The encounter bar doesn't show anymore in dominos, just vanished, one day was there and the other was not, and I tried everything, just when I turn dominos off and reload and turn in again and Im using a dragonring mount it comes back, but soon I leave the mount it disappears again, its a 3 days like this. ( sorry for bad english )

I had the same problem, but I went to the encounter bar in Dominos and clicked on it > Fading > Fade In Opacity bring it to 100. Then it shows your bar fine.
