Seafile customer website password functionality is broken

Steps to reproduce:

  1. register at customer dot seafile dotcom slash accounts
  2. select a very long and complex password. I generated mine with kpasswd dotnet/s/ using a large number of words.
  3. save username and password in a password manager so there is no question of mistyping the credentials. Verify credentials carefully.
  4. confirm account activation email
  5. some time later, attempt to login using credentials saved in password manager.
  6. login doesn’t work. Error is “Incorrect email or password” - which is not possible if the steps above are followed.
    [I would post a screenshot, but I am limited to 1 image in a message.]
  7. attempt to reset the password
  8. result is a server error
