How to display the pagination of the added page on Buddypress

Question

I'm using Buddypress 2.7.2 on Wordpress 4.6.1. I added a new page using the function by bp_core_new_nav_item() on BuddyPress for expanding pages.
On that page, there are ten Post-type artcles each page , the pagination are displayed under the page. However, if I click on page 2 or later of the page, I can not find the link destination. I wrote on the added page as follows.

<?php
$paged = get_query_var('paged');
$args = array(
    'posts_per_page' => 10,
    'paged' => $paged,
    'orderby' => 'post_date',
    'order' => 'DESC',
    'post_type' => 'post',
    'post_status' => 'publish'
);
$the_query = new WP_Query($args);

if ( $the_query->have_posts() ) :
    while ( $the_query->have_posts() ) : $the_query->the_post(); ?>

<?php get_template_part( 'content', get_post_format() ); ?>
<?php endwhile; ?>
<?php
$big = 999999999; // need an unlikely integer

echo paginate_links( array(
    'base' => str_replace( $big, '%#%', esc_url( get_pagenum_link( $big ) ) ),
    'format' => '?paged=%#%',
    'current' => max( 1, get_query_var('paged') ),
    'total' => $the_query->max_num_pages
) );
?>

<?php else: ?>
<?php get_template_part( 'content', 'none' ); ?>
<?php endif; ?>

For example, the pagination link is as follows.
Page 1
Top page is not the problem.
[this is not a link](http://example.com/member/username/custom/
After 2 pages
The link destination does not exist.
[this is not a link](http://example.com/member/username/custom/page/2/ page/3/ page/4/ ........

I don't know why I can not find the 2 page or later. If you know the solution, please let me know.

This is one way to handle pagination in your situation. It is probably not the best or the 'correct' way...

Add the $paged value to the url.

For example:

$paged = ( isset( $_GET['xj'] ) ) ? $_GET['xj'] : 1;
$args = array( ... etc. 

And then adjust your pagination to use that variable:

echo paginate_links( array(
        'base' => esc_url( add_query_arg( 'xj', '%#%' ) ),
        'format' => '',
        'total' => ceil( (int) $wp_query->found_posts / (int) get_query_var('posts_per_page') ),
        'current' => (int) get_query_var('paged'),
    ) );
