After I login from Twitter it just takes me back to this page. If I try to enter the URL of that server it takes me to login page, like the Twitter login didnt happen. With G+ and Youtube it shows that box that I posted in a previous screenshot. Facebook and Yahoo work but I don't have naruto online accounts on those platforms.

I had this same issue and found a fix, albeit a very complicated one, I use a mac so first i had to download a windows parallel software to run windows on a mac, then when you use microsoft edge on windows, you can sign into your twitter for naruto online. After that you will want to go to user center and bind your account to an email, so you no longer have to log in via facebook, twitter, youtube etc. Once your account is binded to an email, you c*e that to login via your normal way (google chrome for me)
