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. [1]: https://i.sstatic.net/bqrD6.png
