In this article, we are going to explore one of the most common WordPress errors known as error 429. We will also talk about troubleshooting the “WordPress 429 too many requests” error. First, let’s start with a basic introduction to this issue:

What Is WordPress 429 Too Many Requests Error?

If you are a webmaster or an owner of a normal WordPress website, nothing can ruin your day like an unexpected error. When you are working on your WordPress website, you may encounter one of the HTTP-status-codes. HTTP-status-codes indicate whether a specific request of the HTTP protocol has completed, successfully. These responses come in five categories:

  1. Informational responses (HTTP-status-code 100 to HTTP-status-code 199)
  2. Successful responses (HTTP-status-code 200 to HTTP-status-code 299)
  3. Redirects (HTTP-status-code 300 to HTTP-status-code 399)
  4. Client errors (HTTP-status-code 400 to HTTP-status-code 499)
  5. Server errors (HTTP-status-code 500 to HTTP-status-code 599)

These HTTP-status-codes are defined by section 10 of RFC 2616, which stands for Request for Comments (RFC). Nearly all protocols, standards, technologies of the internet, and also TCP/IP are described by these documents.

Error 429 is referred to as too many requests error. Unlike other common WordPress errors, error 429 does not give a clue as to the exact cause of the problem.

When a user, script, or bot attempts to make too many requests to the server, error 429 will probably occur. It can also happen when a misbehaving plugin, script, or WordPress theme runs on your site and makes several requests for the server. In this situation, error 429 will cause your WordPress website to become inaccessible. Therefore, it is essential to initiate troubleshooting to fix the error.

You may ask yourself, many requests may mean a lot of traffic on your website; so what is wrong with having many requests? And why too much traffic can cause the HTTP error 429? The answer to this question is simple: sometimes, your web host service by the hosting provider cannot handle such volumes of traffic. Extra traffic is good, but not when your website or server fails to answer all of them.

But what does happen in the process of error 429?

The Process of WordPress Error 429 Too Many Requests

As we mentioned before, HTTP-status-code 429 occurs for a number of reasons. The HTTP error 429 is in the category of client errors, which means sending a request from the client side (user, script, bot) to the server side (website). You probably already know that these requests are made through the HTTP Protocol.

When a client sends too many requests, or when you have a misbehaving plugin or a WordPress theme, or a malfunctioning script is applied on your website, error 429 too many requests occurs. In this situation, the server (website) thinks that all your activities are from a robot attempting a DDoS attack. The practice of error 429 too many requests is sometimes known as “Rate Limiting”.

Rate limiting is used to prevent DDoS attacks (Distributed Denial of Service). This prevention means too many requests have been received by a website or service through API, from a certain user (script, bot, or person). As a result, the server is not willing to respond and process all of these requests. Here, the WordPress error 429 too many requests will occur.

Note that HTTP-status-code error 429 is shown in different ways. The variations of this error can be like the following messages:

  • Error 429 (Too Many Requests)
  • 429 Error
  • 429 Too Many Requests
  • HTTP 429
  • Too Many Requests

Here is an example of HTTP-status-code error 429 that you might see:

HTTP/1.1 429 Too Many Requests
content-type: text/html
Retry-After: 3600

And the HTML code might look like this:

<head> <title>Too Many requests</title>
<body> <h1> Too Many Requests<h1> <p> Only allow 50 requests per hour to this website per logged in user. Try again soon. </p> </body> </html>

Now, let’s see how to fix error 429 too many requests in WordPress.

Fixing 429 Too Many Requests Error in WordPress

As a user, facing the HTTP-status-code error 429, you can do nothing to fix the issue. But as an owner or the administrator of a WordPress website, worrying about DDoS attacks and 429 errors, we have some suggestions for you. We will show you three ways of troubleshooting this HTTP-status-code and fix error 429:

1-Find and Deactivate the Misbehaving Plugin

Nowadays, plugins are used for almost anything. Misbehaving plugins installed on your WordPress site are among the most probable causes for HTTP error 429. However, the problem with misbehaving plugins is finding the one that has caused the 429 error.

To troubleshoot misbehaving plugins related to WordPress 429 too many request errors, deactivating is the first solution. After deactivating all of your WordPress plugins, you should activate them one by one. Activate one of your website plugins and check for the error 429 to see whether it is solved. However, this approach is time-consuming, but you will probably find that misbehaving plugin, and solve that 429 Too Many Requests error.

Once you find the misbehaving plugin, check to see if any settings are changed or not. Sometimes changing the settings is the cause of a plugin misbehaving. If not, contact your plugin creator for the problem, or deactivate it again. Note that it is always best to use as few plugins as possible to make your website fast and convenient. We also suggest that you always install the latest updates of plugins. You can save time by setting up automatic updates.

2- Check Your WordPress Theme

As a WordPress owner, you may prefer dedicated WordPress themes. By ordering one of these dedicated WordPress themes, you can have your desired plugins and install any extension that you wish. Also, your preferred style will be installed on your website. But sometimes, these dedicated WordPress themes may bring you HTTP 429 errors for too many requests.

In this situation, the easiest way is switching your dedicated WordPress theme into a default WordPress theme. If this solves the problem, then you can find another built-in WordPress theme or contact your theme provider to fix the error.

3- Ask Your Hosting Provider

If these steps do not fix the HTTP 429 error, then contact your hosting provider. Sometimes, the issue is not from your side. The problem may be caused by a third party (i.e. hosting provider). Although DDoS attacks are a possibility, more often it is your hosting provider that has received many requests from search engines and has raised the 429 error.

As you know, search engines use bots to determine the proper rank of your website. On the other hand, some web-hosting providers may block requests from specific third party platforms or services (such as crawlers, search engines, and other applications such as Google Search Console). These request blocking may cause a large number of requests to your websites. So, to fix the 429 Too Many Requests error, contact your hosting provider and ask them to allow these requests, to solve the problem.

In Conclusion

HTTP-status-code error 429 is one of the most common WordPress errors that can cause you trouble. In this article, we described some useful ways, including deactivating misbehaving plugins, changing your dedicated WordPress theme into a default theme, and contacting your hosting provider, to fix the error. You can also change your default login URL, or check whether WordPress HTTP internal links (HTTP-status-code 500) are causing the issue.

Overall, if you encounter an HTTP-status-code error 429 too many requests, you most likely need to reduce the number of received requests on the server. Try one of our suggested methods mentioned in this article. They will probably fix the error.
