not able to move to next month view, even though an event is scheduled

As is, I cannot move to the next month view, even though there is an event scheduled. I read in a thread to add the following in my functions.php file. Still no luck. Am I missing something?

/**
 * Allows visitors to page forward/backwards in any direction within month view
 * an "infinite" number of times (ie, outwith the populated range of months).
 */
 
if ( class_exists( 'Tribe__Events__Main' ) ) {
 
  class ContinualMonthViewPagination {
      public function __construct() {
          add_filter( 'tribe_events_the_next_month_link', array( $this, 'next_month' ) );
          add_filter( 'tribe_events_the_previous_month_link', array( $this, 'previous_month' ) );
      }
 
      public function next_month() {
          $url = tribe_get_next_month_link();
          $text = tribe_get_next_month_text();
          $date = Tribe__Events__Main::instance()->nextMonth( tribe_get_month_view_date() );
          return '<a data-month="' . $date . '" href="' . $url . '" rel="next">' . $text . ' <span>&raquo;</span></a>';
      }
 
      public function previous_month() {
          $url = tribe_get_previous_month_link();
          $text = tribe_get_previous_month_text();
          $date = Tribe__Events__Main::instance()->previousMonth( tribe_get_month_view_date() );
          return '<a data-month="' . $date . '" href="' . $url . '" rel="prev"><span>&laquo;</span> ' . $text . ' </a>';
      }
  }
 
  new ContinualMonthViewPagination;
 
}
