I always use Yahoo account as open ID to login in my superuser account but it was working fine till yesterday after that it is saying **No OpenID endpoint found**.

I want to know why this problem is coming. I tried Firefox, chrome but none of them worked.

Well then I used **login using Stack Exchange** and used forget password option and created a new password, it worked and I was logged in.
