 * Hello [@jannetto96](https://wordpress.org/support/users/jannetto96/),
 * I hope you’re doing well!
 * This is a warning that says that the advanced-cache.php file can not be found.
   Please go to **Hummingbird > Caching > Page Caching** deactivate Page Cache and
   activate it again to recreate the advanced-cache.php file.
 * The Deactivate button is located at the bottom of the page Caching page. Please
   see this screenshot:

 * Let us know how it went!
 * Kind regards,
    Nastia
