title: jekyll page build failure
body: <p>I'm new to web development, so please bear with me.</p>
  <p>I'm trying to create a website for a group project using Github Pages, and I have forked <a href="https://github.com/swcool/landing-page-theme" rel="nofollow noreferrer">this repository</a>. I've made several changes, and the website was up and running. Today I updated some images and the website wouldn't build anymore. I tried reverting to the previous commit, but it wouldn't build either. I read the troubleshooting page, to no avail. I don't have any idea of what to do anymore, please help.</p>
  <p>the error:</p>
  <blockquote>
  <p>The page build failed with the following error:</p>
  <p>Page build failed. For more information, see help[dot]github.com/articles/troubleshooting-github-pages-build-failures.</p>
