Error Wp Rest Server.php

  • 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. 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.
