With WoW closed, browse to World of Warcraft Classic\WTF\Account\%your account name%\NostalriusBegins\%your character name% and delete the chat-settings.txt file that's in there. Relaunch WoW, login, select your character, and see if your chat works properly. Also verify it created a new chat-settings.txt file in that same folder after you login.
