Locales and links not working as intended
If your entry's slug is en/contact and you need it to show up when you go to the URL domain.com/en/contact/en/contact, the Section settings for the Entry URL Format should be en/contact/{slug}:



Also, you shouldn't need to use the language code prefix (en/) in Section settings. That should be defined in your config/general.php file. See the Define your site URLs section of the Craft 2 docs on localization.

return array(
    // ...
    'siteUrl' =&gt; array(
        'en' =&gt; 'http://example.com/en/',
        'no' =&gt; 'http://example.com/no/',
    ),
);


Then, if you Section's URL settings are contact/{slug}, these URLs will both work:

http://example.com/en/contact/en/contact
http://example.com/no/contact/en/contact
