Octopress blank page when add backtick code block

Question

I am wondering why I am getting blank page when I add backtick code block with specific language?

_config.yml

markdown: rdiscount
rdiscount:
  extensions:
    - autolink
    - footnotes
    - smart
pygments: false # default python pygments have been replaced by pygments.rb

in my post If I use backtick without specific language

```
var foo = "Hello";
```

that's working, page is shown normally

but When I use backtick with specific language ex.js, javascript, java

```js
var foo = "Hello";
```

It's blank page without errors.

I think it works fine on Ubuntu but didn't work on Windows 7
Any suggestions ?

Fenced code blocks with a language specifier are only supported in the very latest version of Discount / RDiscount (2.1.7). Make sure your RDiscount gem is >=2.1.7.
