 * Fatal error: Cannot declare class WP_REST_Blocks_Controller, because the name
   is already in use in /homepages/8/d487188190/htdocs/wp-content/plugins/gutenberg/
   lib/class-wp-rest-blocks-controller.php on line 123

 * Gutenberg is now “the block editor” and part of WordPress 5.x. You don’t need
   to install a plugin unless you want the leading-edge changes before they get 
   moved into core. Via FTP or your hosting control panel’s file manager app, delete
   the directory `wp-content/plugins/gutenberg`.
