By default, the forum description will only show on the forums archive page. 

You can use the following function code to add a forum description when viewing a single-forum page (within a group / standalone forum).

Please follow the steps below:

1. Go to Appearance > Theme Editor.

2. Under “Select theme to edit”, choose (BuddyBoss Child/whatever theme is active), then click “Select”.

3. Below Theme Files, select Theme Functions (functions.php).

4. Append the code just before the closing PHP tag “?>”:

function bbp_singleforum_description() {
  echo '<div class="bb-forum-content-wrap"><div class="bb-forum-content">';
  echo bbp_forum_content();
  echo '</div></div>';
}
add_action( 'bbp_template_before_single_forum' , 'bbp_singleforum_description');

5. Click Update File to save the changes.
