Nostalrius Begins - Quality wow vanilla realm (1.12)

I cant speak in general chat. If I type /1 nothing happens and it brings me the "type /help for a list of commands." I have a horde toon and am able to chat on them but unable to on alliance.. I am super confused on why I can't join any channels. Please help.

Its a Bug on this Server. Just relog and it will work again.

An easier method is to /leave <channel> /join <channel>
