Nostalrius Begins - Quality wow vanilla realm (1.12)

I'm new to the game, and my general, trade, say and yell channels doesnt work. I can read but I cant type.

I tried relogging, deleting the wtf folder and leaving and rejoining the channels, but nothing seems to work. Does anyone happen to know what causes this?

Try disabling all addons

This is the spam filter kicking in. Wait with chatting until you are level 10-15ish, or you risk a ban :-s

I think it let me start using /say when I was level 5. I thought everyone was just really quiet until I got tried to talk and realized there was a level restriction. You can still talk in /party if you're grouped.
