My Mojang account won't link with my Twitch account.

Ok so when I try to link my MOJANG account to my Twitch account, it says to log in but when I do, my information disappears and nothing happens. I login on Twitch.tv THEN I go to the Authorize Application page, then I see this "Authorize app for (My name)", I click it, nothing happens. Can someone help, because I've been trying this since yesterday and it won't work.
Just in case, my Minecraft username is Sam1212cube (which is migrated)
