Lordaeron Lua Error while oppening MAP

[Kikii]

When open MAP I get 'Lua Error' and can't use it, can't see quests or anything.

*I deleted chache and it didn't help.
*I'm not using any addon, it's regular clear Blizz UI.

Weird fact is that on all my other characters on that account I can use map without problems but I can't use it on one of them, just that one has problems.

Anyone got idea how to fix it? Moderator told me he doesn't know how to assist with this problem and adviced me to post this here..

There might be some problem with a quest that you have on that character. Try completing or abandoning your quests.

It helped. I just abandoned all quests I had from Terrokar Forest zone and it works fine now.
Thanks for help ^^

Advice: When you come to Terokkar Forest on Lordareon while leveling after taking EVERY quest try to open MAP and see if it happens to you, if it does skip that quest, if not just continue with leveling / doing quests.
Cheers!
