WordPress is a wonderful platform. Here you can create your blog or website and publish your thoughts or promote your business on the web. But, like any other content management system (CMS). WordPress also has glitches and errors that you will face with this platform.

WordPress REST API errors are the most common WordPress errors. These errors can cause your site to go offline and make it difficult to manage. These are usually caused by a plugin conflict or a misconfigured server. This guide will provide you with some of the most common WordPress REST API errors and how to fix them. But before that, let’s have a glance at what REST API is:

REST API-An Overview!

Many developers might not be aware of WordPress REST API because it is unnecessary to create a WordPress site that works. Most WordPress sites are built with the help of themes and plugins and are created in PHP. Developers who would prefer to build their site using a different technology. Some of them who wish to create a mobile application that uses data from their site may find this a limitation.

In these circumstances, you can access all the same data as you would in PHP using the REST API, which is independent of language and framework. The API supports all the latest programming languages and is used with any language for parsing JSON answers and making HTTP queries.


But, if you use the REST API, particularly for the first time on a new site, you may come across some issues. Even while some of these mistakes are frequent, there are easy fixes. Let’s now proceed with what we have created this guide actually for; the most common WordPress REST API Errors and how to fix them:

1. Bad Permalink Settings:

The first issue that may crop up is a bug in the permalinks functionality. This error occurs because of security settings; hence you need to change them so that the WordPress REST API can work. Permalinks create a permanent and unique link for each post or page. You must ensure that you have set the correct option for the same. (Settings > Permalinks)

2. Disabled API:

Your site may be using a shared or public IP address or could be misconfigured, in which case the REST API will not work for your site. Some of the reasons for this include is; if your website does not have a valid SSL certificate. If it is not loading the header (header.php), is missing WordPress’s CNAME file, or has a corrupted .htaccess file.

3. General Errors:

Apart from the permalink setting, there are other issues. The general errors category includes file permissions, security settings, and server timeouts. These can be fixed by making simple changes to your WordPress site. To fix these errors, check whether they are causing your mistake.


While WordPress REST API errors are expected, you can fix them by following these steps. Finally, a word of caution: check for all these errors if you are having issues with your site. If you find these errors, before moving ahead, make sure you fix these errors or take help from professionals.
