I added the below script in my website to set up a custom language slug like th, se etc.

After adding this below script my pages are working like.

– http://www.mywebsite.com/
– http://www.mywebsite.com/se/
– http://www.mywebsite.com/th/

Issue: but my blog pagination like throwing 404 error.

– http://www.mywebsite.com/blog/page/2
– http://www.mywebsite.com/se/blog/page/2
– http://www.mywebsite.com/th/blog/page/2

Script custom permalink and rewrite rules:

    /*---------------Page permalinks ---------------*/
        add_filter( 'page_link', 'prefix_custom_link_option', 10, 3 );
        
        function prefix_custom_link_option($link, $post_id , $sample){
        	global $wp_rewrite;
            $category = get_the_terms($post_id, "nk-post-translation");
        	$post = get_post($post_id);
        	if (!empty($category) && $category[0]->slug == "th") {
        	    $link = str_replace(home_url(),home_url('th'), $link);
        	} elseif (!empty($category) && $category[0]->slug == "se") {
        		$link = str_replace(home_url(),home_url('se'), $link);
        	} else {
        		$link = str_replace(home_url(),home_url(), $link);
        	}
        	return $link;
        }
        
        
        /*-----------------page rewrite rule -----------*/
        add_filter('page_rewrite_rules', 'my_new_page_rewrite_rules');
        function my_new_page_rewrite_rules($page_rewrite) {
