Since you mention that no user accounts work, you will need to reset the administrator password from recovery mode. There is already an excellent Q&A describing this so I won't reiterate that here (see below).

When you have logged into the administrator account, you can reset the user ICE-Authority file as follows:

Open a terminal cd /home/[user account] where [user account] is the name of the account - for example paul

i.e. cd /home/paul

then

sudo chown paul:paul .ICEauthority
sudo chmod 0644 .ICEauthority

logout and then login to the paul account.
