Title: REST API ERRORS Last modified: August 16, 2020 --- # REST API ERRORS * [jasonsahli](https://wordpress.org/support/users/jasonsahli/) * (@jasonsahli) * [5 years, 10 months ago](https://wordpress.org/support/topic/rest-api-errors/) * `Notice: register_rest_route was called incorrectly. The REST API route definition for nv/v1/posts/page/(?P\d+) 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.

There are various default endpoints for the API. The API can also be extended. * That error message means that one of the REST API endpoints your site uses, isn’t doing a permissions check. This isn’t necessarily a security issue, but you should check if the information displayed at the endpoint is supposed to be public. * Hope this helps. * Moderator [Samuel Wood (Otto)](https://wordpress.org/support/users/otto42/) * (@otto42) * WordPress.org Admin * [5 years, 10 months ago](https://wordpress.org/support/topic/rest-api-errors/#post-13264591) * The error is coming from a plugin or theme which needs to be updated. Look through your plugins or themes for something that might be called “nv”. * In the meantime, this is a Notice only, so ask your host how to properly disable the “display_errors” setting in your PHP install. * Thread Starter [jasonsahli](https://wordpress.org/support/users/jasonsahli/) * (@jasonsahli) * [5 years, 10 months ago](https://wordpress.org/support/topic/rest-api-errors/#post-13264667) * My Friends: Thanks for the kind and helpful words. My nv theme (neve) is already running the running the latest version so still not sure how to correct this other than to notify the theme provider of the issue and see if they can fix it. * [Carike](https://wordpress.org/support/users/carike/) * (@carike) * [5 years, 10 months ago](https://wordpress.org/support/topic/rest-api-errors/#post-13264707) * Please notify the theme provider 🙂 You can also refer them to the REST API channel on Slack, if they are unsure. This error message was added specifically to help make sites more private (and in some cases, a lot safer). Again, this does not necessarily mean that there is a problem, as the information may need to be public, but it is something that the developer should check. If it is intended to be public, they should add __return_true to the function – that will remove the warning message. * Thread Starter [jasonsahli](https://wordpress.org/support/users/jasonsahli/) * (@jasonsahli) * [5 years, 10 months ago](https://wordpress.org/support/topic/rest-api-errors/#post-13264784) * I will follow this helpful advice and thank u for being good wp stewards for help with this issue. - This reply was modified 5 years, 10 months ago by [jasonsahli](https://wordpress.org/support/users/jasonsahli/). * [Ari Stathopoulos](https://wordpress.org/support/users/aristath/) * (@aristath) * [5 years, 10 months ago](https://wordpress.org/support/topic/rest-api-errors/#post-13266021) * [@jasonsahli](https://wordpress.org/support/users/jasonsahli/) The Neve theme has a class called `Pagination`. Inside that class, they have a method called` register_endpoints`. Inside the `Pagination->register_endpoints()` method they are calling the `register_rest_route` function, and in the arguments they pass to it they don’t include a `permission_callback` as the error you’re getting mentions. Judging from their code, the callback they are performing doesn’t get any private data so they can simply add this line in their arguments to make it work properly: `'permission_callback' => '__return_true',` So the end code on that method would look like this: * ``` public function register_endpoints() { register_rest_route( 'nv/v1/posts', '/page/(?P\d+)/', array( 'methods' => \WP_REST_Server::CREATABLE, 'callback' => array( $this, 'get_posts' ), 'permission_callback' => '__return_true' ) ); } ``` * You can contact your theme theme-author with that information so they can fix it. 🙂 * [Alexei Suzdalenko](https://wordpress.org/support/users/alexeisuzdalenko/) * (@alexeisuzdalenko) * [5 years, 5 months ago](https://wordpress.org/support/topic/rest-api-errors/#post-13842370) * thank you very much you helped me a lot Viewing 7 replies - 1 through 7 (of 7 total) The topic ‘REST API ERRORS’ is closed to new replies. * In: [Fixing WordPress](https://wordpress.org/support/forum/how-to-and-troubleshooting/) * 7 replies * 5 participants * Last reply from: [Alexei Suzdalenko](https://wordpress.org/support/users/alexeisuzdalenko/) * Last activity: [5 years, 5 months ago](https://wordpress.org/support/topic/rest-api-errors/#post-13842370) * Status: not resolved ## Topics ### Topics with no replies ### Non-support topics ### Resolved topics ### Unresolved topics ### All topics
