title: What's exactly wrong with this mkdocs.yml configuration?
body: <p>I am working on a MkDocs project and trying to tweak the markdown_extensions setting. Please look at it and tell me what's wrong, since I really can't find the error.
  <strong>Note: I have installed the required libraries, so that isn't the problem.</strong></p>
  <pre class="lang-yaml prettyprint-override"><code>  - markdown.extensions.codehilite:
      css_class: highlight
    - markdown.extensions.extra: {}
    - markdown.extensions.fenced_code: {}
    - markdown.extensions.md_in_html: {}
    - markdown.extensions.meta: {}
    - markdown.extensions.nl2br: {}
    - markdown.extensions.tables: {}
    - markdown.extensions.toc:
      title: 
    - pymdownx.emoji:
      title: long
    - pymdownx.tasklist: {}
  </code></pre>
  <p>By the way, I'm using the ponylang theme.</p>
