I used Sage v. 5.0 for the first time in a while and couldn't connect to the notebook. I received the message: Firefox can't establish a connection to the server at localhost:8000.
I was still able to use Sage from the command line, but decided to install v. 5.11 to see if that would fix my problem.
In fact, it did; and now the notebook opens at localhost:8080.
Does anyone know the reason for this?
