Hi Giovanni,

When I export the following code block

,----
| #+begin_src emacs-lisp :exports both
|   :foo
| #+end_src
`----

it generates the following HTML.

,----
| <pre class="src src-emacs-lisp"><span style="color: #d0d0ff;">:foo</span>
| </pre>
| 
| 
| <pre class="example">
| :foo
| </pre>
`----

My guess is that during export you get a message along the lines of
"htmlize is required for export".  Try explicitly loading htmlize.el (in
the contrib/lisp directory of org) and then re-exporting and you should
get the desired output.

Best,
