Question

I have data being displayed from a custom post type and has pagination below it but for some reason the pagination is not getting displayed.

Answer 1

use the_posts_pagination which wp provides for pagination. (number of posts to show is defined from the admin panel's given number - posts per page ) example :

<?php the_posts_pagination( array(
                                                                'mid_size' => 2,
                                                                'prev_text' => __( 'Previous page', 'findarch' ),
                                                                'next_text' => __( 'Next page', 'findarch' ),
                                                                'screen_reader_text'    => __('navigation','findarch')
                                                                ) ); ?>
