displaying-recent-questions php code not working

Hi Rahul,

I used the php code you gave here, http://anspress.io/questions/question/displaying-recent-questions/

added to my theme index.jsp page, but it throws error

Fatal error: Call to a member function have_posts() on a non-object in D:\xampp\htdocs\test\wp-content\plugins\anspress-question-answer\includes\question-loop.php on line 182

i am using latest version of wordpress, theme is from https://roots.io/sage/

could you please let me know what might be wrong? thanks

<?php
ap_get_questions(array('showposts' => 5));
?>
 
<?php if ( ap_have_questions() ) : ?>
  <div class="ap-questions">
    <?php         
      /* Start the Loop */
      while ( ap_questions() ) : ap_the_question();
        ap_get_template_part('content-list');
      endwhile;
    ?>
  </div>
<?php ap_questions_the_pagination(); ?>
<?php
  else : 
    ap_get_template_part('content-none');
  endif; 
?>
