Top menu does not refresh with language change

Hi everyone,

I’ve got some troubles with my top menu. It stays in french even if I change the language for English.

There are 2 menus: french/english and only 2 pages: one in french/one in english (and for these page, The switch of language is OK)

I assigned each menu to its language

I updated this in header.php:
<?wp_nav_menu( array( ‘container_class’ => ‘menu-header’, ‘theme_location’ => ‘primary’ ) ); ?>

But it still doesn’t work. Polylang seems to be really cool but I don’t undertsand … I saw a multilingual forestly-theme website using Polylang, so I guess it could work.

I use Striker free Theme, but the problem appears with forestly theme or 2015 theme.

Thank you in advance for your help.
DrEVil, Fr
