Hi Dan Lee,

Please navigate to Dashboard > Forums > Dashboard, click on "Update Forums Statistic", then delete all caches, do CTRL + f5 on frontend. If it doesn't help let us know. 

Still the same @sofy

This is a specific case. wpForo doesn't display last post info stat if that info comes from a forum which is private for regular visitors (guests). To make it available for registered users you should put this code in WordPress theme functions.php file.

function wpforo_fix_footer_stat_for_private_forum( $stats ) {
    if(function_exists('WPF')){
        $posts = WPF()->topic->get_topics(array('orderby' => 'modified', 'order' => 'DESC', 'row_count' => 1, 'private' => 0, 'status' => 0 ));
        $key = key($posts);
        if ( wpfval($posts, $key) ) {
            $stats['last_post_title'] = $posts[$key]['title'];
            $stats['last_post_url'] = WPF()->post->get_post_url($posts[$key]['last_post']);
        }
    }
    return $stats;
}
add_filter( 'wpforo_get_statistic_array_filter', 'wpforo_fix_footer_stat_for_private_forum');

How to Easily Add Custom Code in WordPress (without Breaking Your Site)

IMPORTANT: Once you put this code, please navigate to Dashboard > Forum Dashboard admin page and click on [Delete all caches] and [Update Forum Statistic] buttons.

This worked, thanks.
