I am trying to load my jekyll site locally, but get the errors below. I am unsure where to start, since there are so many errors.
(base) ➜  angoodkind.github.io git:(master) ✗ bundle exec jekyll serve

jekyll 3.5.2 | Error:  Liquid syntax error (line 8): Unknown tag 'when'
I have an index.html file both in my base directory, as well as in my blog/ subdirectory. Which file(s) should I look at? Any and all direction is greatly appreciated.
