Can't login the WoW Classic server when Simplified Chinese selected as text language

Dscale,

We fixed this a little while ago actually and we don’t have the problem when we test on our end. Can you check your build of classic for us? It should display next to the “Play” button. (Version #.##.#.#####) - can you tell us what that number is for you?

Have you tried logging in using English, and does it make the problem go away?
