WP_Query 'orderby' => 'rand' isn't working for a custom post type


can anyone please advise why this is not working? It is just showing the same post each page refresh rather than a new random one from the list.

<?php $loop = new WP_Query( array(
'post_type' => 'testimonials',
'posts_per_page' => 1,
'orderby' => 'rand' ) );

<?php while( $loop->have_posts() ) : $loop->the_post(); ?>

<div class="quote_bubble"><?php the_content(); ?></div>										

<div class="speech_bubble_credit"><?php the_field('testimonial_name'); ?><br />

<?php the_field('testimonial_job_company'); ?>, <?php the_field('testimonial_company'); ?></div>

<?php endwhile; wp_reset_query(); ?>

Open in new window

This is just displaying the first post I added to the site again and again every time page is refreshed too if that is of any use in trying to establish the problem.

Any ideas anyone please?

Where are you hosted? Some ISPs disable the rand function because it takes too many resources.

Thought so!

WP Engine does disables rand.  Log in as administrator and go to the WP Engine tab for the site.  There should be a checkbox to re-enable it.
