I tried changing my avatar picture here on Pagure (as part of the Fedora team), but ran into an error:

After logging in, I land on the profile page with the basic information like my user name and full name and my current avatar: https://pagure.io/settings#nav-basic-tab.

Clicking on "Change Avatar" leads to the page https://www.libravatar.org/account/login/ results in a blank page with the text "Not Found The requested resource was not found on this server".

Someone on the Fedora team mentioned that the correct page should be https://www.libravatar.org/accounts/login/.
