There seems to be a problem with your history database. Find your history.sqlite. It should be here:

~/.ipython/profile_default/history.sqlite

Rename or remove it and try to start the notebook server again.

I get a "Permission denied" warning when I entered your offered comment. What should I do? Thanks. @MikeMüller – Stomatal

Did you stop all of your notebook servers before renaming/removing the file? – Duckboard

In case someone's wondering, I used ipython locate profile default command as told here for locating the history.sqlite file – Corm
