Probably just a long-shot but you have the last version installed really? There is also a call to wp_head() in your header.php?

OK thanks!

Very good! I committed it 2 days ago. That might be the reason 😉

Please check if version 1.1 works for you.

Please indicate the website 😉

Yes, it is. Do you need help with that?

You can map them via code (in your functions.php for example):

function my_msls_options_get_permalink( $url, $language ) {
    $locale = get_locale();
    $needle = '/product/';
    switch ( $locale ) {
        case 'es_ES':
            $url = str_replace( $needle, '/producto/', $url );
            break;
        case 'it_IT':
            $url = str_replace( $needle, '/prodotto/', $url );
            break;
    }
    return $url;
}
add_filter( 'msls_options_get_permalink', 'my_msls_options_get_permalink', 10, 2 );
