For that, you need to paste the following code snippet into the functions.php file of the Olympus child theme:
/** * Set Activity Comments Length - Show the latest 0 comments. */function yzc_set_activity_comments_length() { ?> <script type="text/javascript">window.youzify_comments_length = 0;</script> <?php}add_action( 'wp_head' , 'yzc_set_activity_comments_length', 999 );You can change "0" number to any else.
