The following code now returns nothing on the category.php template, used to work fine. I use this code on multiple sites:
<php while (have_posts()) : the_post(); ?>
<h3 class="text-center"><?php the_title(); ?></h3/>
<?php the_field('r4m_video_url'); ?>
<?php if ( get_field( 'r4m_video_description') ): ?>
<?php the_field('r4m_video_description'); ?>
<?php endif; ?>
<?php endwhile; ?>
‘r4m_video_url’ is a text field for iframe code.
Any ideas what is causing the error?
