 * Hi! When I access to “edit page” or “create new page” I get this message:
 * “Warning: array_intersect_key(): Expected parameter 1 to be an array, string 
   given in ./wp-includes/rest-api/class-wp-rest-server.php on line 1402”
 * It is a multisite if it could be some help.
 * I can access to edit and create but this message is giving me some more waiting
   time when loading the page.
 * Thanks!

 * This may be a plugin or theme conflict. Please attempt to disable all plugins,
   and switch to the default Twenty Twenty-One theme. If the problem goes away, 
   enable them one by one to identify the source of the problem.
 * If you can install plugins, install [Health Check](https://wordpress.org/plugins/health-check/).
   On the troubleshooting tab, you can click the button to disable all plugins and
   change the theme for you, while you’re still logged in, **without affecting normal
   visitors to your site**.
