 * Notice: register_rest_route was called incorrectly. The REST API route definition
   for wordpress-popular-posts/v1/popular-posts is missing the required permission_callback
   argument. For REST API routes that are intended to be public, use __return_true
   as the permission callback. Please see Debugging in WordPress for more information.(

 * Hi [@wabelman](https://wordpress.org/support/users/wabelman/),
 * Yes, another user reported this issue not long ago: [register_rest_route was called incorrectly](https://wordpress.org/support/topic/register_rest_route-was-called-incorrectly-3/).
   Please check the comment I left there for a temporary fix until version 5.2.4
   is ready for release.
