On servers for Minecraft I can not chat.  It has been 2 years since this started happening and its annoying.  I can still chat on my games, but on all servers I cant.  I assumed it was a bug to be fixed, but it was never fixed, and I could be muted, but I doubt it.  It's just on Minecraft, and has nothing to do with my account.  So it's a chat bug.  I've tried everything to fix it, nothing works.
