Pagination not working

(copy of my reply to the same question in another thread)
Just faced with the same question.
Quick searching over internet showed there’s no known solution (at least that I could find).
I looked into the plugin and was able to tune it to show the pagination.
I think I will leave the solution here just in case someone will be searching for the same in the future (unless the plugin is upgraded to embed the solution).
NB: The solution requires basic knowledge of PHP and WordPress architecture, since it includes plugin source code adjustment.
NB2: The solution describes an unconditional pagination inclusion. If you need to be able to switch pagination on / off, elaborate the solution further.

there are two steps required to achieve the goal:
a) adjust WP variables to turn standard pagination workflow on
b) adjust page template to display pagination

Ok now, here are the modifications (based on plugin version 4.9.3)
1) in file inc/core/shortcodes.php, in function posts(), add the following line
$GLOBALS[‘wp_query’] = $posts;
after the initialization of the $posts variable ($posts = new WP_Query( $args ))
this will setup WP global variable wp_query used in standard pagination generation functions.
2) same function, add
wp_reset_query();
line before this call: wp_reset_postdata()
this will reset the above modification after the pagination is printed
3) same function, find the $atts array initialization in the very beginning and ‘paged’ argument to the initialization array:
‘paged’ => get_query_var(‘paged’) ? get_query_var(‘paged’) : 1
this will tell the query current page index to display
4) add pagination output to the templates/default-loop.php file (or the other template you are using). You can use standard WP functions for that (function posts_nav_link(), I added it to the end of the template).

Hope this wasn’t too complicated ??

I have the same problem. shikh, I would love to apply your fix but I cannot follow your instructions. Is it possible for you to upload these changed files or maybe give the line numbers?

Here is how function posts() looks for me in inc/core/shortcodes.php now:

public static function posts( $atts = null, $content = null ) {
		// Prepare error var
		$error = null;
		// Parse attributes
		$atts = shortcode_atts( array(
				'template'            => 'templates/default-loop.php',
				'id'                  => false,
				'posts_per_page'      => get_option( 'posts_per_page' ),
				'post_type'           => 'post',
				'taxonomy'            => 'category',
				'tax_term'            => false,
				'tax_operator'        => 'IN',
				'author'              => '',
				'tag'                 => '',
				'meta_key'            => '',
				'offset'              => 0,
				'order'               => 'DESC',
				'orderby'             => 'date',
				'post_parent'         => false,
				'post_status'         => 'publish',
				'ignore_sticky_posts' => 'no'
			), $atts, 'posts' );

		$original_atts = $atts;

		$author = sanitize_text_field( $atts['author'] );

as for the template change, there’s nothing more than putting posts_nav_link() wherever you want the pagination to appear

thanks.. I’ll give it a shot.. I actually just reread all of this and realized it may not be my exact problem. My problem is the gallery not showing pagination but it could be this. Trying now…
