Paging isn’t working when looking up search result.

Thank you for interesting in our product and your feedback. We appreciate it.

I sent and notified our technical team about this problem. We are checking and fixing.

Any your suggestion will make our product become better and better.

Thanks for your report. Just a quick note that we are fixed this bug.

In addition, I want to share a small tip, so you can apply it on your WordPress website.

I realize that even when you use the pretty permalinks, WordPress does not still rewrite the search results URL. Then I try to type:

http://designwall.com/search/sidebar/page/2/

I get a search results page with actual results for the search term “sidebar”. So the function exists but the rewrite rule does not. I added the following code to theme functions:

add_action('template_redirect', 'dw_search_url_rewrite_rule');
function dw_search_url_rewrite_rule() {
    if ( is_search() && !empty($_GET['s'])) {
        wp_redirect( home_url("/search/") . urlencode(get_query_var('s')). '/' );
        exit();
    }   
}

And now, it worked well for me. Try this suggestion and let me know result.
