Please try using the following hook code. Insert it into the active theme's functions.php file:

const WPD_RUO_CACHE_DOMAIN = "wpd_registered_only";

  function wpd_ruo_tag_recent_comments_args( $args ) {
      $args = WPD_RUO_CACHE_DOMAIN;

      return $args;
  }

  add_filter( "wpdiscuz_widget_recent_comments_args", "wpd_ruo_tag_recent_comments_args" );

  function wpd_ruo_filter_comment_clauses( $clauses, $query ) {
      if ( WPD_RUO_CACHE_DOMAIN !== ( $query->query_vars ?? "" ) ) {
          return $clauses;
      }

      global $wpdb;
      $clauses .= " AND {$wpdb->comments}.user_id > 0";

      return $clauses;
  }

  add_filter( "comments_clauses", "wpd_ruo_filter_comment_clauses", 10, 2 );

Great question! For wpDiscuz specifically, you're in luck — the plugin includes a Recent Comments widget that you can use to display a user's recent comments. However, since you're looking to aggregate activity from multiple plugins (wpDiscuz, wpForo, and LearnDash) on a single dashboard, you'll likely need a more comprehensive approach.

Here are a few strategies to consider:

• Use wpDiscuz's Recent Comments Widget: This is the built-in solution for wpDiscuz activity, and it can be placed in a widget area on your dashboard page.
• Create a custom dashboard page: You might want to explore using a page builder (like Elementor or Beaver Builder) combined with custom code to query user activity from all three plugins and display it in one unified view.
• Check for dashboard plugins: There are some user dashboard plugins that work with multiple activity sources — you could look into whether any support all three of your plugins.
• Custom shortcode development: If you have development resources, creating a custom shortcode that queries user activity across all three plugins would give you the most control and flexibility.

Have you already explored the wpDiscuz widget options, or are you specifically looking for a way to combine all three plugin activities into a single shortcode? That would help me point you toward the best solution for your setup.

We'll check and get back to you ASAP.
