I last logged in about 2 months ago, on 4-12-2017. Today on 6-7-2017 I logged in again and the chat icon was greyed out and both chats are inaccessible. I have tried refreshing and reloading the page several times and the problem persists. (Hopefully) linked here is a screenshot of the greyed out icon. I am level 46 and can assure you that I am past the tutorial portion of the game where the chat is disabled.
Image didn't do great, here's a URL:
