 * Hi,
 * My site is: [http://www.hortusvarius.com/](http://www.hortusvarius.com/)
 * As you will I am having a few problems with it. Whenever I go to the homepage
   or wp-admin page I am greeted by this message:
 * > Fatal error: Class ‘WP_Widget’ not found in /customers/a/0/8/hortusvarius.com/
   > httpd.www/wp-includes/widgets/class-wp-widget-pages.php on line 17
 * I have done a manual reinstall of WordPress, I have disabled all my plugins and
   I have done a manual change of the template back to twentyfifteen.
 * I have also added this code to my debug.log but don’t understand how to fix the
   response:
 *     ```
       // Enable WP_DEBUG mode
       define( 'WP_DEBUG', true );
   
       // Enable Debug logging to the /wp-content/debug.log file
       define( 'WP_DEBUG_LOG', true );
   
       // Disable display of errors and warnings
       define( 'WP_DEBUG_DISPLAY', false );
       @ini_set( 'display_errors', 0 );
   
       // Use dev versions of core JS and CSS files (only needed if you are modifying these core files)
       define( 'SCRIPT_DEBUG', true );
       ```
   
 * None of these have fixed the issue, any helpe would be greatly appreciated.
 * Thanks,
 * Anthony
