 * Hi in my wordpress admin I am receiving this error:
 * Warning: array_map(): Expected parameter 2 to be an array, bool given in /home/
   customer/www/mywebsite.it/public_html/wp-content/plugins/wordpress-seo/inc/class-
   wpseo-meta.php on line 1013
 * I have a WordPress Multisite with Multilingualpress and this issue occurs only
   in the English version of my website.
 * The website is private, so if you need to check it I would need to send you the
   credentials in private.
 * Thanks
    Regards

 * Hi [@lorey80](https://wordpress.org/support/users/lorey80/),
 * Given the warning messages, we suspect that the data stored in the Yoast indexable
   table in the WordPress database may be outdated or invalid. Can you please try
   the following steps:
 * 1. Install the [Yoast Test Helper](https://wordpress.org/plugins/yoast-test-helper/)
   plugin,
    2. Go to Admin > Tools > Yoast Test and 3. Click the `Reset indexables
   tables & migrations` button 4. After clearing out the indexable data, we re-ran
   the site-wide scan under Admin > SEO > Tools and clicked the ‘Start processing
   and speed up your site now’ button. This may take a few minutes depending on 
   the size of your site.
 * Does the issue resolve?

   require any further assistance please create a new issue.
