 * After I tried to upgrade my website to WordPress 5.0.3, I got an error which 
   was related to wp-config.php and fixed it. Then I found that I can not edit my
   custom_taxonomy posts. When I try to edit, I get following error message:
 *     ```
       Warning: array_reduce() expects parameter 2 to be a valid callback, function 'rest_preload_api_request' not found or invalid function name in /opt/bitnami/apps/wordpress/htdocs/wp-admin/edit-form-blocks.php on line 75
   
       Fatal error: Uncaught Error: Class 'WP_Block_Type_Registry' not found in /opt/bitnami/apps/wordpress/htdocs/wp-admin/includes/post.php:2045 Stack trace: #0 /opt/bitnami/apps/wordpress/htdocs/wp-admin/edit-form-blocks.php(112): get_block_editor_server_block_settings() #1 /opt/bitnami/apps/wordpress/htdocs/wp-admin/post.php(168): include('/opt/bitnami/ap...') #2 {main} thrown in /opt/bitnami/apps/wordpress/htdocs/wp-admin/includes/post.php on line 2045
       ```
   
 * Thanks in advance for your help.

 * When you updated, did you update all the files? Including the WordPress root 
   files, like wp-settings.php?
 * If you didn’t update all the files, then not everything is loaded, and you’re
   missing classes and such. Do a complete manual update.
