Hi,
Copy the template from wp-content/plugins/a-z-listing/templates/a-z-listing.php
into your theme (e.g. copy it to wp-content/themes/<your-theme>/a-z-listing.php
).
Now you can edit the copy in your theme to change line 58 that reads <?php $a_z_query->the_title(); ?>
. You should get suitable results by changing it to:
<?php $a_z_query->the_title(); ?> (<?php $a_z_query->the_item_post_count(); ?>)
It is worth noting that if your theme is not one that you created yourself (such as one of the default WordPress themes, a theme from www.ads-software.com, or one from a third-party) then you likely will benefit from creating a child theme so that any updates to the theme aren’t going to cause this situation from happening again.
