You must go to adress http://cp.pandawow.ru/ and login there. Then there is a tab "Исправить персонажа" - click. You'll see you characters list, please choose your character, which stucks and click "Продолжить" , then you can see a button "Починить" - click. Delete a Cache folder in your WoW dirrectory, then login in the game. The problem should be resolved after these manipulations.
