Localization - linking to other pages goes to 404
First off, make sure you have .htaccess files in both the en and fr folders and this per the localization guide.

Secondly, you're missing a comma in the siteUrl array:

'siteUrl' =&gt; array(
    'en' =&gt; 'http://etf-craft.dev/en/',
    'fr' =&gt; 'http://etf-craft.dev/fr/' &lt;--------add comma here-----
),
