Are you using any addons for chat?

[malynn90]

Im using no chat addons and am having a similar issue. Cant party chat, cant see rolls, cant see if I won a roll, can not participate in general or trade chat of any kind. Cannot even whisper another player Started a couple days ago and only affects one of my toons.
No clue what this is
