[Ultimatedmg]

Hello,
I have a problem, 2 day ago my exp bar disappeared and i dont get any experience points for kill mobs / quest / instance.
I relog game (many times), on my second character I have this same problem.
I disable all addons, dont help.
I have 42 lvl.

Please help.

Theres a chance you accidently locked your XP with the NPC in SW/Orgrimmar?
If that's the issue you can unlock it with the same NPC.
he is on the room with the BG npcs in both SW and Org, stealthed in the corner.

Wow, I did not know that it was possible to block the experience. I was looking for a trainer from daggers and had to accidentally block. Of course you were right, thank you so much for your help. I will now be more careful with who I am talking to.
Thank you very much for your help once again.
