Experience bar disappear

Hi, i cannot get my experience bar back with Slahtz in Orgrimar. I cant leveled my toon anymore.

Yeah i have a 49 tauren that i stalled the grind so i can enjoy legion more but now i cant undo what i did with Slahtz.

:frowning: that sad

What do you see in the dialog box when you talk to Slahtz? No option to turn your XP back on? Any other message?

Edit: looks like this is a bug others are experiencing and a fix is suggested here: Experience Eliminator no longer turning ON xp - #8 by Fangdangle-jubeithos

Can confirm, this definitely works!
