Archive pagination not working

I’m attempting so as to add pagination for my Archive. I need to present 12 posts per web page after which present the ‘subsequent’ / ‘earlier’ buttons.

Once I manually change the worth of the $paged variable, the 1 right into a 2 it really works.
Once I click on the Subsequent button on the archive web page, it masses a really bizarre theme web page. The url appears to be like like: ‘/web page/2/’.

What am I doing incorrect?

That is the code I wrote up to now:

<?php
  international $paged,$wp_query;

    $paged = (get_query_var('paged')) ? get_query_var('paged') : 1;

    $args = array(
        'post_type' => 'realisaties',
        'posts_per_page' => 12,
      'paged' => $paged,
        'order' => 'ASC'
    );

    $archive_query = new WP_Query($args);

    whereas ($archive_query->have_posts()) : $archive_query->the_post();

      $picture = get_field('preview_afbeelding');

      if( !empty($picture) ):

        $url = $picture['url'];
        $title = $picture['title'];
        $alt = $picture['alt'];
        $caption = $picture['caption'];

        // thumbnail
        $dimension = 'medium';
        $thumb = $picture['sizes'][ $size ];
        $width = $picture['sizes'][ $size . '-width' ];
        $top = $picture['sizes'][ $size . '-height' ];

        if( $caption ): ?>
          <div class="wp-caption">
        <?php endif; ?>
        <div class="col-md-3">
          <?php echo get_the_title(); ?>
          <a href="<?php the_permalink() ?>" title="<?php echo $title; ?>">
            <img class="realisatie-img img-responsive" src="<?php echo $thumb; ?>" alt="<?php echo $alt; ?>" title="" width="<?php echo $width; ?>" top="<?php echo $top; ?>" />
            <br />
          </a>
        </div>

        <?php if( $caption ): ?>
        <h2> <?php echo get_the_title(); ?></h2>
        <p class="wp-caption-text"><?php echo $caption; ?></p>
        </div>
      <?php
      endif;
      endif;
    endwhile;
    ?>


<?php next_posts_link('Older Entries »', $archive_query->max_num_pages); ?>
<?php previous_posts_link('Newer Entries', $archive_query->max_num_pages); ?>
<?php wp_reset_query(); ?>
</div>
</div>
