5 Methods to Fix the 413 Request Entity Too Large Error


413 Request Entity Too Large error is one of the most common issues that users may come across when managing a WordPress website.

This error occurs when the server is unable to process a request due to the size of the data.

Fortunately, there are several solutions available to address this problem.

In this article, we will explore various methods to fix the 413 Request Entity Too Large error in WordPress and get your website up and running smoothly again.

What causes the 413 error?

Client request

The 413 Request Entity Too Large error occurs when a client (usually a web browser) sends a request to a server.

The server is unable to process it because the size of the data being transferred exceeds the server’s configured limitations.

This error is specifically related to the size of the entity (such as a file) that is uploaded or transmitted through the request.

Web Server Configuration

File size

Web servers typically have certain limitations set to prevent abuse and ensure efficient resource allocation.

These limitations include restrictions on the maximum size of data that can be uploaded or transmitted in a single request.

If the size of the entity exceeds these predefined limits, the server will respond with a 413 error.

PHP File Settings

Upload size limit and following code

In WordPress, the server-side scripting language PHP plays a crucial role.

PHP has its own configuration settings that control various aspects of file uploads, including size limits.

If the PHP settings for maximum file upload, maximum allowed size or maximum post size are set too low.

It can trigger the 413 error when attempting to upload larger files.

Web Application Firewall (WAF)

Apache server

Some websites employ security measures such as a Web Application Firewall.

This can also impose limitations on the size of requests.

If the WAF is configured to restrict large entity sizes, it may intercept the request and trigger the 413 error.

Proxy Servers or Load Balancers

In some cases, websites are hosted behind proxy servers or load balancers that also enforce limitations on request sizes.

If the entity file size exceeds all the limits set by these intermediaries.

They may reject the request and generate a 413 error.

It’s important to note that the specific causes of the 413 error can vary depending on the server setup and configuration.

Identifying the underlying cause is crucial in order to implement the appropriate solution and resolve the error effectively.

How does it affect your WordPress website?

It is important to ensure that your WordPress website can handle the expected file sizes and accommodate the needs of your users.

Negative Impact on SEO and User Experience

This can adversely affect your website’s search engine rankings and visibility.

In summary, the 413 Request Entity Too Large error can impede uploads, affect website functionality, limit content management options, and have negative consequences for user experience and search engine optimization.

5 Methods to Fix the 413 Request Entity Too Large Error

1) Adjusting PHP Settings

Maximum upload size

One of the common causes of the 413 error is restrictive PHP settings that limit the maximum file upload size and post size.

By adjusting these settings, you can increase the allowable limits.

  1. Accessing the php.ini file

Locate the php.ini file in your server’s root directory.

If you can’t find it, check with your hosting provider or look for alternative methods specific to your hosting environment.

  1. Modifying the upload_max_filesize directive

Within the php.ini file, find the line that contains the upload_max_filesize directive.

Increase the value to a higher limit, such as “20M” for 20 megabytes.

Save the changes.

  1. Changing the post_max_size value

In the same php.ini file, locate the post_max_size directive and adjust it to a value larger than the upload_max_filesize.

For example, set it to “25M” if you increased the upload_max_filesize to “20M”.

Save the changes.

  1. Restarting the server

After making the modifications, restart your web server for the changes to take effect.

By restarting your web server, you ensure the application of the new PHP settings.

Using an FTP client or the File Manager in your hosting control panel, locate and open the .htaccess file in the root directory of your WordPress installation.

Remember to create a backup of the file before making any changes.

  1. Adding or modifying code snippets

Insert the following lines of code at the beginning or end of the .htaccess file:

php_value upload_max_filesize 20M
php_value post_max_size 25M
php_value memory_limit 64M

You can adjust these values according to your requirements.

Save the changes to the .htaccess file.

  1. Saving the changes and testing the website

After modifying the .htaccess file, save it and try uploading the large file again.

Check if the 413 error still happens.

If not, proceed to the next method.

3) Modifying Nginx Configuration

  1. Accessing the Nginx configuration file

Locate the Nginx configuration file, which is typically nginx.conf or default.conf.

You can find it in the /etc/nginx/ directory.

  1. Adding or modifying client_max_body_size value

Within the configuration file, find the http block and add or modify the client_max_body_size directive.

Set it to a value that accommodates your own file size and upload requirements, such as “20M” for 20 megabytes.

  1. Reloading Nginx configuration

After making the changes, save the file and reload the Nginx configuration by running the following command: sudo service nginx reload or sudo systemctl reload nginx in your terminal or command prompt.

4) Contacting Your Hosting Provider

If you prefer a more user-friendly approach, you can utilize WordPress plugins specifically designed to manage uploads and handle large file sizes.

  1. Exploring WordPress plugins

In the WordPress Plugin Directory or through reputable third-party sources, search for plugins that address file upload limitations or optimize file handling.

  1. Installing and configuring a plugin to manage file uploads

Choose a suitable plugin and install it on your WordPress site following the standard plugin installation procedure.
