 * Hi,
 * I’ve installed the plugin in hoping it could help improving the response time
   of wp rest api. I have implemented a custom endpoint and added in the plugin’s
   settings. However, it seems like nothing is cached because there is nothing in
   the ‘Endpoint API Caches’. What could go wrong and how do I go about fixing it?
 * Thank you!

 * Hi [@saigonhelper](https://wordpress.org/support/users/saigonhelper/)
 * Thank you for using our plugin!
 * One possible reason could be that the necessary must-use plugin isn’t created
   when activating the plugin. Could you check if the file `wp-rest-cache.php` exists
   in your `/wp-content/mu-plugins/` directory?

 * Hi,
    Yes, it’s in there. What else should I check?

 * Hi [@saigonhelper](https://wordpress.org/support/users/saigonhelper/)
 * If I look at the headers of your website if I request the posts endpoint (`/wp-
   json/wp/v2/posts`) I do see the `X-WP-Served-Cache` header, which suggests it
   is being cached.
