 * I’m also getting a similar warning for line 90.
 * Attempt to read property “post_title” on null in /home/customer/www/website/public_html/
   wp-content/plugins/hide-page-and-post-title/hide-page-and-post-title.php on line
   90
 *     ```wp-block-code
                        public function hpt_hptloadscripts(){                  global $post;---> line 90      $this->title = $post->post_title;                   if( $this->hpt_ishidden() ){wp_enqueue_script( 'jquery' );}    }
       ```
