After installing BTTV whole chunks of content are missing from the Twitch home page (http://i.imgur.com/m7t3hLc.png), going to any page such as /directory/following produces blank white pages (http://i.imgur.com/NRxTyOh.png). Going to a channel page produces the same blank white page, there is however a black line indicating where the side bar is (http://i.imgur.com/duFO4WR.png). What’s worse is that the problem persists even after uninstalling BTTV and restarting my computer.
First I thought it was my ad-blocker, disabling it and restarting had no effect. Now here I am unable to use Twitch at all on Safari!
