 * You can read about the REST changes here: [https://make.wordpress.org/core/2020/07/22/rest-api-changes-in-wordpress-5-5/](https://make.wordpress.org/core/2020/07/22/rest-api-changes-in-wordpress-5-5/)
 * > In [[48526]([https://core.trac.wordpress.org/changeset/48526](https://core.trac.wordpress.org/changeset/48526))]
   a _doing_it_wrong notice has been added when a permission callback is omitted.
   For REST API routes that are intended to be public, it is recommended to set 
   the permission callback to the __return_true built in function.
 * _Running WordPress 5.5 beta4._
 * See example notice:
 *     ```
       PHP Notice:  register_rest_route was called <strong>incorrectly</strong>. The REST API route definition for 
       <code>pll/v1/languages</code> is missing the required <code>permission_callback</code> argument. For REST API routes that are 
       intended to be public, use <code>__return_true</code> as the permission callback. Please see 
       <a href="https://wordpress.org/support/article/debugging-in-wordpress/">Debugging in WordPress</a> for more information. 
       (This message was added in version 5.5.0.) in /usr/local/wordpress/wp-includes/functions.php on line 5225
       ```
   
 * This will happen for all pll/ routes.

 * Hello,
 * As you are obviously using Polylang Pro, please note that the support of premium
   plugins is not allowed in this forum. You should use our helpdesk [https://polylang.pro/support/](https://polylang.pro/support/)
   instead.
 * That said, we are of course already aware of this and it is already fixed in 
   the beta of Polylang Pro 2.8 that you can download from your account.

 * Oh, my apologies. I forgot the REST endpoint was a PROD addon. Will check out
   2.8-beta.
