Hi there,

Before your continue with further steps please consider reading the article we wrote about How to Add Custom Code to your site. Then please past the code below in function.php

remove_action('kalium_blog_single_post_details_after','kalium_blog_single_post_prev_next_navigation', 20);
add_action( 'kalium_blog_single_post_details_after', 'kalium_blog_single_post_prev_next_navigation_custom', 31 );
if (! function_exists('kalium_blog_single_post_prev_next_navigation_custom')) {
    function kalium_blog_single_post_prev_next_navigation_custom(){
        if ( kalium_blog_get_option( 'single/prev_next' ) ) {
            // Args
            $args = array();
            $adjacent_post_args = apply_filters( 'kalium_blog_single_post_prev_next_navigation', array(
                'return' => 'id',
                'loop' => true
            ) );
            $prev_id = next_post_link_plus( $adjacent_post_args );
            $next_id = previous_post_link_plus( $adjacent_post_args );
            // Previous link
            if ( $prev_id ) {
                $prev = get_post( $prev_id );
                $args['prev'] = $prev;
                $args['prev_title'] = __( 'Newer Post', 'kalium' );
            }
            // Next link
            if ( $next_id ) {
                $next = get_post( $next_id );
                $args['next'] = $next;
                $args['next_title'] = __( 'Older Post', 'kalium' );
            }
            kalium_get_template( 'global/post-navigation.php', $args );
        }
    }
}

Hi Texussa,

Can we try this one below :

remove_action('kalium_blog_single_post_details_after','kalium_blog_single_post_prev_next_navigation', 20);
add_action( 'kalium_blog_single_post_details_after', 'kalium_blog_single_post_prev_next_navigation_custom', 99 );
if (! function_exists('kalium_blog_single_post_prev_next_navigation_custom')) {
    function kalium_blog_single_post_prev_next_navigation_custom(){
        if ( kalium_blog_get_option( 'single/prev_next' ) ) {
            // Args
            $args = array();
            $adjacent_post_args = apply_filters( 'kalium_blog_single_post_prev_next_navigation', array(
                'return' => 'id',
                'loop' => true
            ) );
            $prev_id = next_post_link_plus( $adjacent_post_args );
            $next_id = previous_post_link_plus( $adjacent_post_args );
            // Previous link
            if ( $prev_id ) {
                $prev = get_post( $prev_id );
                $args['prev'] = $prev;
                $args['prev_title'] = __( 'Newer Post', 'kalium' );
            }
            // Next link
            if ( $next_id ) {
                $next = get_post( $next_id );
                $args['next'] = $next;
                $args['next_title'] = __( 'Older Post', 'kalium' );
            }
            kalium_get_template( 'global/post-navigation.php', $args );
        }
    }
}

Thank you.
