I believe this to be caused by commit 796c5d7 where $navbar-light-color was set to $navbar-dark-color but I couldn't find where $navbar-dark-color was defined anywhere. I ended up forking the project and fixing this by changing it back to the way that @thatmattlove had it previously using $darkest instead of $navbar-light-color.

If you would like to see the quick fix I made on my server, here is the link to the commit on my fork:

I'd be happy to open a quick PR if you'd like to pull this in. Thanks!
