Disclaimer, I have no idea what any of these dependencies are or what they do, whatsoever. I did bundle update and made some random changes to gemfile until I was able to run the guides app locally.

¯\_(ツ)_/¯

Definitely deploy to staging before merging. I will also test this in a clean environment. ~It will be a miracle if the Travis build passes.~ Somehow it passed. Yay?

I am relatively sure this will horribly break because our code is not compatible with middleman 4 🤔

I dunno, it runs ok... I will try moving it to 3 and see what happens

I updated only the activerecord version and that seems to fix it.
