Nostalrius Begins - Quality wow vanilla realm (1.12)

My chat is bugged on one character but not on another. I cant see anything i type in my log, I know other people are getting it. Also all the other channels.

Delete the chat settings file in your World of Warcraft Classic\WTF\Account\%character name% folder for your character that's bugged. It'll recreate and use default chat settings the next time you open WoW and login.
