Pagination in single.php

In order for pagination to work on the page of one post, you need to put this code in the functions.php file:

 

add_action( 'template_redirect', 'single_post_second_loop_pagingation_fix', 0 );
    function single_post_second_loop_pagingation_fix() {
        if ( is_singular( 'post' ) ) {
            global $wp_query;
            $page = ( int ) $wp_query->get( 'page' );
            if ( $page > 1 ) {

                    $query->set( 'page', 1 );
                    $query->set( 'paged', $page );
            }
            remove_action( 'template_redirect', 'redirect_canonical' );
        }
    }
