I have collected all the dragon riding glyphs on my main, but i am unable to use them on my alt- a level 63. I go to the dragon riding ability screen and i click the abilities, but they do nothing, just stay grey. I have tried the recommended reset Blizzard has posted with the addon deletion and the folder renaming but that did not work. Does anyone know how to fix this??? 
Ah man, sorry guys I am just an IDIOT… have to click the top circle to learn that one before you can do anything else ;_; my brain dumb.
