Pagination with WordPress default gallery?

Question

Here is the part of code handling pagination in functions.php:

// Pagination Setup $current = (get_query_var('paged')) ? get_query_var( 'paged' ) : 1; $per_page = 3; $offset = ($current-1) * $per_page; $big = 999999999; $total = sizeof($attachments); $total_pages = round($total/$per_page); if( $total_pages < ( $total/$per_page ) ){ $total_pages = $total_pages+1; } // Pagination output $output .= paginate_links( array( 'base' => str_replace($big,'%#%',esc_url(get_pagenum_link($big))), 'format' => '?paged=%#%', 'current' => $current, 'total' => $total_pages, 'prev_text' => __('&laquo;'), 'next_text' => __('&raquo;') ) ); 

Here is the page:

The issue:

The code successfully divides images into groups by three, creates pages for these groups, creates pagination numbers and creates links to the pages. But when I click on any pagination link, I do not go anywhere.

Although when the page ( https://www.motorizm.net/bugatti-type-41-royale/ ) has "Status: Draft", pagination links do work as they are supposed to.

Any ideas?

Ended up like this. Made this changes and it worked:

changed:

'base' => str_replace($big,'%#%',esc_url(get_pagenum_link($big))), 

into:

'base' => get_permalink( $post->post_parent ) . '%_%', 

And changed:

'format' => '?paged=%#%', 

into:

'format' => 'paged=%#%', 

Then added a filter with rewrite tag and rule:

add_filter('init', 'post_gallery_add_rewrite_tag_rule_2022'); function post_gallery_add_rewrite_tag_rule_2022() { add_rewrite_tag('%current%','([^&]+)'); add_rewrite_rule('([^/]+)/paged=/?([0-9]{1,})/?$', 'index.php?name=$matches[1]&paged=$matches[2]', 'top'); } 

Then (after uploading functions.php) in WordPress admin panel:

Settings -> Permalinks -> [ Save Changes ]
