Hello
 
	Barrowing the thread, im having the same issue.
 
	I leveled to 35, and suddenly i couldnt use any chat functions anymore, (emotes does work)
 
	I logged on to my 60 warrior on the PVP server and that character could chat.
 
	Im having problems with my horde character on Nostalrius PVE Server (Level 35 Undead Mage Nessum)
