 * Just updated. These appear on every admin page:
 *     ```
       PHP Notice:  Undefined index: register_meta_box_cb in /wp-content/plugins/custom-post-type-generator/custom-post-type-generator.php on line 281
   
       PHP Notice:  Undefined index: show_in_rest in /wp-content/plugins/custom-post-type-generator/custom-post-type-generator.php on line 285
   
       PHP Notice:  Undefined index: show_in_rest in /wp-content/plugins/custom-post-type-generator/custom-post-type-generator.php on line 336
       ```
   
 * Need to re-save all CPT and taxonomies to remove notices.
