 When editing a page in the Gutenberg editor (that is built-in, not the
 plugin), I see this Warning on a page:
 ```
 <b>Warning</b>:  array_intersect_key(): Expected parameter 1 to be an
 array, string given in <b>/home/cosydale/public_html/ovirium.com/wp-
 includes/rest-api/class-wp-rest-server.php</b> on line <b>1402</b><br />
 ```

 Disable REST plugin is not installed.
