Hey William,
I am sorry for the delay of this reply,
I have temporary disable that Twitter login button from backend first.
By the way, I've trying to login with your FTP server, It seems like your FTP access is not working, please advise.
By the way, in the future you can just include your site's access once at
http://stackideas.com/dashboard/site rather than needing to keep adding them in your replies.
