Please set up a reduced testcase:

You're most likely just missing your NProgress container.
martinratinaud commentedon Sep 10, 2015
This happens when you start a NProgress with a custom selector for Settings.parent and you change page (this happens to me with angular).
Nprogress will remove the progress bar after a certain timeout (based on
speed) and this means that if you change the page and selector does not exists anymore, nprogress.remove() will be fired anyway, resulting in the above error.I made a PR for that #129
Cheers

I can confirm that Martinratinaud's commit has changed the problem (at least, for me). :)

This issue is already solved into the master javascript file, but not released until now.
