title: org-mode - no syntax highlighting in exported HTML page
body: <p>I've been trying to get the syntax highlighting to work when exporting org-mode formatted file to HTML, but none of what I've done so far has worked. I followed the <a href="http://orgmode.org/worg/org-contrib/babel/languages.html#configure" rel="noreferrer">Babel configuration guide</a> but the code block on the generated HTML page still looks plain. I have also set <code>(setq org-src-fontify-natively t)</code>. What am I missing?</p>
