WordPress分页无法正常工作

Question

I'm facing a problem with WordPress pagination. Tried almost every answer of Stackoverflow and other sites, but nothing works. What happens is: the next/prev redirect me to 404 when I click (in my case shows me my homepage because I don't have one 404). The URL changes to .../page/2 but shows my homepage.

Here is my code, its a specific category template "category-blog.php".

 <div class="col-xs-12 col-sm-8 col-md-8 col-lg-8 blogPost">
  <?php if ( have_posts() ) : while (have_posts() ) : the_post(); ?>
  <div class="post" style="overflow:hidden;margin-bottom:30px">
    <h2 class="searchResults">
      <?php the_title(); ?>
      -
      <?php the_time('d/m/Y') ?>
    </h2>
    <div class="col-sm-6"> <a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>">
      <?php $image = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ), 'single-post-thumbnail' ); ?>
      <img src="<?php echo $image[0]; ?>" title="" alt="" class="img-responsive"> </a> </div>
    <div class="col-sm-6">
      <?php the_excerpt(); ?>
      <a href="<?php the_permalink() ?>" class="btn btn-primary">Read more</a></div>
  </div>
  <?php endwhile; ?>
  <div> </div>
  <?php else : ?>
  <p>
    <?php _e( 'Sorry, nothing found.' ); ?>
  </p>
  <?php endif; ?>
</div>

Thanks in advance!
