 * Hello!
 * A few days ago, one of the microsites we have in a multisite installation lost
   its configuration. I deleted and reinstalled the Flash theme, and now some of
   the “Customize” submenus are not available.

 * Also others microsites that use the Flash Theme are given me the following error:
 * **Fatal error**: Uncaught TypeError: array_merge(): Argument #3 must be of type

 * Hi [@jrbarboza](https://wordpress.org/support/users/jrbarboza/),
   We’ve already
   fixed the issue you mentioned. It looks like you’re using an outdated version
   of the theme. Please update to the latest version and clear all caches.
 * I hope this helps!
 * Best regards,
