304 Status Code: Meaning and Ways to Resolve it

Are you worried about the 304 status code? No need, we will help you understand the HTTP 304 error and also how to fix it.

A poor server page can lead to an error. You might have noticed some numbers pop up sometimes when you open a webpage, something like Error codes 301, 404, 409, and so on.

To remove these doubts, we have brought a series of these Errors or I should say, HTTP status codes.

304 Status Code

The 3XX status code represents redirection, thus, the HTTP 304 Status code comes under the same category. There are a lot more status codes that fall under the 3xx category with each one having different indications.

  1. 300 – Multiple Choice
  2. 301- Moved Permanently
  3. 302- Found
  4. 303- See other 
  5. 304- Not Modified
  6. 305- Use proxy 
  7. 306- Switch Proxy
  8. 307- Temporary Redirect
  9. 308- Permanent Redirect

Now, let us study the  ‘304- NOT MODIFIED’ status code in brief.

It indicates that the requested resources have not been modified since the last time you visited the page. In this case, the server redirected the user to see the cached version of the resource. It may be an issue from either the server side or the client side.

You can’t always consider 304 codes as errors, they can help improve user experience since the information is already cached, and they can help Google Bots crawl other web pages.

In this guide, we have explained 304 code errors, their causes, and ways to resolve them.

Also: Have you experienced 409 Error before?

Why Does HTTP 304 Occur

The HTTP 304 error is a client (visitor) error, meaning, the error is at the end of a visitor. Here are the possible reasons why. 

  • Malware and Viruses 

304 errors can be caused by malware. It could be the case that the user’s PC is malware infected and it is causing the error. 

  • Browser History and Cache 

Sometimes our browser history is responsible for 304 not modified messages. As the cache can become full, leaving no space for new resources. 

  • Corrupted files in the browser

Corrupted files can be generated on our browser that can stop the browser from saving or updating information as it should.

  • Issues with third-party application

Browser versions, plugins, or any faulty third-party applications can also be a cause for 304 errors.

For Website Owners: Check .htaccess file 

It could be that the issue is in your server configuration files, so it is recommended to check your .htaccess files. Follow the steps below to do so.

Step 1- Open your cPanel 

Step 2- Go to the file manager

Step 3- Search public_html, which is the root directory of your website

Step 4- Locate the .htaccess file. You may have to enable show hidden files in the file manager to see it.

Step 5- Select the .htaccess file and click on Rename.

Step 6- Rename it as .htaccess_disabled

Step 7- Save the changes

Check if the website is functioning properly.
