[Polylang] Homepage shows posts in both languages

Hi,

I have a compatibility problem between Polylang v0.9.4 and the PhotoGrid Free Responsive theme from https://www.dessign.net

I have defined 3 languages (Japanese, French and English), and all posts in different languages show on the homepage (not a static page). Everything is fine when I revert to the Twenty Ten basic theme. My website is managed locally (on my hard drive).

As I’ve been reading a few threads before creating this one, here’s the content of my index.php:

<?php get_header(); ?>

    <h3 class="top_title">
    </h3>

    <div id="content_inside">

    <?php
    $category_ID = get_category_id('blog');
    $args = array(
                 'post_type' => 'post',
                 'posts_per_page' => 9,
                'post__not_in' => $slider_arr,
                 'cat' => '-' . $category_ID,
                 'paged' => ( get_query_var('paged') ? get_query_var('paged') : 1)
                 );

    query_posts($args);
    $x = 0;
    while (have_posts()) : the_post(); ?>                        

        <?php if($x == 2 || $x == 5 || $x == 8 || $x == 11 || $x == 14 || $x == 17 || $x == 20 || $x == 23 || $x == 26 || $x == 29 || $x == 32 || $x == 35 || $x == 38 || $x == 41 || $x == 44) { ?>

            <div class="home_post_box home_post_box_last">

        <?php } else { ?>
            <div class="home_post_box">
        <?php } ?>

            <a>" class="home_post_text_back"></a>
            <a>"><?php the_post_thumbnail('home-image'); ?></a>
            <a>" class="home_post_text">

                <h4><?php the_title(); ?></h4><h3><?php the_excerpt(); ?></h3>

            </a><!--//home_post_text-->

        </div><!--//home_post_box-->    

        <?php if($x == 2 || $x == 5 || $x == 8 || $x == 11 || $x == 14 || $x == 17 || $x == 20 || $x == 23 || $x == 26 || $x == 29 || $x == 32 || $x == 35 || $x == 38 || $x == 41 || $x == 44) { ?>

            <div class="clear"></div>

        <?php } ?>

    <?php $x++; ?>

    <?php endwhile; ?>        

    <div class="clear"></div>

    </div><!--//content_inside-->

    <div class="clear"></div>

    <div align="center" class="load_more_cont"><?php next_posts_link(' ') ?></div>

    <?php wp_reset_query(); ?>
        <h3 class="top_title">
    </h3>

<?php get_footer(); ?>

Thanks for your time!
