What is 414 Request URI Too Long Error and How to Fix It

As a WordPress expert with over 15 years of experience, I’ve seen my fair share of errors. But the ‘414 Request URI Too Long’ error is one that often stumps even seasoned developers. This error occurs when a URL or an action you’re requesting is too long for the server to handle. It can be a real headache for website owners, potentially disrupting user experience and hindering your website’s performance.

Don’t worry, though! This article will break down everything you need to know about the 414 error, from its causes to detailed solutions. I’ll also provide some expert tips and tricks to prevent this error from happening in the first place. So, let’s dive in and get your website back up and running smoothly.

Understanding the 414 Request URI Too Long Error

The ‘414 Request URI Too Long’ error is an HTTP status code indicating that the requested URL is too long for the server to process. It’s important to understand the difference between URI (Uniform Resource Identifier) and URL (Uniform Resource Locator). A URI can be a resource’s name, location, or both, while a URL is simply the location of a resource. While both terms are often used interchangeably, it’s important to remember that URLs are a part of URIs.

In the context of the 414 error, it’s essential to understand that both the URI and URL components can trigger this error. Now, let’s explore the reasons behind this frustrating issue.

What Causes the 414 Request URI Too Long Error?

When dealing with WordPress errors, identifying the root cause is crucial for finding the right solution. Here are some common culprits behind the ‘414 Request URI Too Long’ error:

UTM Parameters: UTM (Urchin Tracking Module) parameters are commonly used to track conversions on your WordPress website. If you’re using a lot of these parameters in your URLs, they can significantly increase the URL length, potentially triggering the 414 error.
Redirect Loops: Redirect loops occur when a misconfiguration or a plugin setting causes a series of redirect requests. This can lead to incredibly long URLs, often resulting in the ‘414 Request URI Too Long’ error.
Plugins: Certain plugins can generate lengthy URIs as part of their functionality. Security plugins are particularly notorious for causing this issue due to their complex security measures.
Developer-Side Issues: In rare cases, a developer-side issue can cause a 414 error. This might happen when a POST request mistakenly turns into a GET request, leading to a URL with excessive query information.
Cyber Attacks: Cyber attacks on your web server can also trigger 414 errors. These attacks often involve manipulating your website’s functionality to cause errors and disrupt your website’s operations.

Now that you understand the potential causes, let’s move on to fixing this pesky error and getting your website back on track.

Fixing the 414 Request URI Too Long Error

The quickest solution to the ‘414 Request URI Too Long’ error is to increase the maximum URI size that your website server can handle. Before we dive into the technical fixes, it’s crucial to create a WordPress backup. Editing website configuration files can be risky, and a backup provides a safety net in case something goes wrong.

Here’s a step-by-step guide to fixing the 414 error:

1. Determine if Your Website is Using Apache or Nginx

First, you need to identify the type of server that your WordPress website is using. The two most common server types are Apache and Nginx. Here’s how to find out:

Open your website in a web browser.
Right-click on the homepage and select “Inspect” (or similar, depending on your browser).
Switch to the “Network” tab at the top.
Select any element under the “Name” column.
Scroll down to the “Response Headers” section and look for the “Server” detail.

The “Server” detail will indicate whether you’re using Nginx or Apache. If you’re still unsure, reach out to your WordPress hosting provider for clarification. Once you know your server type, you can proceed with the appropriate fix.

2. Fixing 414 Request URI Too Long Error in Nginx

If your website uses Nginx, you’ll need an FTP client to access website configuration files. Filezilla is a popular FTP client you can use. If you need assistance setting up FTP and accessing your website files, refer to our guide on how to use FTP to upload files to WordPress.

Download the nginx.conf file: Navigate to the following path using your FTP client: /etc/nginx/nginx.conf. Download the file to your computer.
Edit the file: Open the downloaded nginx.conf file in a text editor (like Notepad or TextEdit).
Increase the URI limit: Search for the “large_client_header_buffers 4 8K” settings. If you don’t see this setting, add it to the end of the file. Change the size from 8K to 128K. This will increase the maximum URI size that your Nginx server can handle.
Save and re-upload: Save the changes to the nginx.conf file and upload it back to your website using your FTP client.

3. Fixing 414 Request URI Too Long Error in Apache

The process for fixing the 414 error in Apache is similar to the Nginx fix.

Download the apache2.conf file: Use your FTP client to navigate to the following path: /etc/apache2/apache2.conf. Download the file to your computer.
Edit the file: Open the downloaded apache2.conf file in a text editor.
Increase the URI limit: Look for the “LimitRequestLine 128000” settings. If you don’t see this setting, add it to the end of the file. You can increase the limit to 256000 or higher (make sure the value is a multiple of 2). This will allow your Apache server to handle longer URIs.
Save and re-upload: Save the changes to the apache2.conf file and upload it back to your website using your FTP client.

After making these changes, the ‘414 Request URI Too Long’ error should be resolved. If the issue persists, consider exploring other potential causes and solutions.

Expert Tips for Preventing 414 Errors

Here are some expert tips to help you prevent the ‘414 Request URI Too Long’ error in the future:

Use a URL shortener: If you’re using UTM parameters for tracking, consider using a URL shortener service like Bitly or Goo.gl. This will reduce the length of your URLs and help prevent the 414 error.
Review your plugins: Regularly check your installed plugins and ensure they’re up-to-date and not contributing to long URIs. Consider disabling plugins one by one to see if any are causing the issue.
Optimize your redirect chains: Avoid long redirect chains by simplifying your website’s structure and minimizing unnecessary redirects. This will ensure that URLs don’t become excessively long.
Monitor your server logs: Regularly review your server logs for any suspicious activity or errors. This can help you identify and address potential issues before they become major problems.
Contact your hosting provider: If you’re still struggling with the 414 error, don’t hesitate to contact your WordPress hosting provider for assistance. They can often provide more specific guidance based on your server configuration.
