[Solved through hack] Can't login or change password because the current password has less than 10 characters.
EDIT: I was able to solve this by going into the “change password” screen, right-clicking the “old password” field, clicking “inspect”, and changing maxlength=“60” minlength=“10” to maxlength=“60” minlength=“1”, thanks to the tip provided by Dandroid in the comments....
