In my research for the implicit grant flow authorization, I was seeing this js error in the web inspector tool on page load of the Twitch Log in (https://api.twitch.tv/kraken/oauth2/authorize?response_type=token&client_id=…):
TypeError: 'undefined' is not a function (evaluating 'l.bind(this,o,c)')
I understand that the .bind() js function is kind of ‘newish’ that probably wouldn’t be supported in the older webkits. (Confirmed with a new Qt version (5+) that the Twitch login page would per just dandy.)
Today, I just tried authorizing Twitch on a Qt4.8.2 webkit build and it appears to be working again. Something must have changed on Twitch’s end recently for this log in page? Is it working for you now @GamersBoss777 and @DeezjaVu?
