Hey Tim
I took a look.
There was definitely some issue with your pagination function….
I replaced your pagination in archive.php
with a standard WP function, and it seems to work out of the box (locally).
In your archive.php
, around line 74 you have –
<?php pagination_bar(); ?>
Lets replace this with a WP one, which looks just the same as your pagination:
<?php
echo the_posts_pagination( array(
'prev_text' => __( '« Previous', 'twentyfifteen' ),
'next_text' => __( 'Next »', 'twentyfifteen' ),
) );
//old pagination
//pagination_bar();
?>
And there you go 🙂 works great here.
Sometimes a theme or plugin will modify WP pagination functions using filters, and switching to another WP function for pagination usually seems to solve the issue when this arises with S&F 🙂
Thanks
