When a user makes a request and there is a mismatch with the available pages, the website will display a 404 Not Found error. There are several common forms of the 404 Not Found code, including the following:

• 404 Error
• Error 404
• HTTP 404
• 404 Not Found
• HTTP 404 Not Found
• 404 Page Not Found
• Error 404 Not Found
• 404 File or Directory Not Found
• The requested URL was not found on this server

What Can Cause a 404 Not Found Error?

There are several potential causes for a 404 Not Found error, including the following:

1. Incorrect URL Entry

The 404 Not Found error most commonly occurs due to a typo in the URL. This also typically happens when the URL has been updated but not reflected in certain menu links on the website. It can also occur because the URL in question has been permanently deleted.

2. Errors in Website Plugins or Themes

Additionally, errors in the plugins or themes used on the website can also trigger a 404 Not Found error. The cause is that issues with the plugin can affect the URL links.

3. Caching Errors

The third cause: a 404 Not Found error can appear due to caching issues. This happens when the browser you’re using cannot find the website’s cache file it’s looking for.

4. DNS Configuration Issues

Finally, a 404 Not Found error can also appear if you forgot to point your domain to the server. As a result, the domain you own has not yet been propagated to the DNS. This situation can also be referred to as the resolution phase.

How to Fix a 404 Not Found Error on Your Website?

The good news is that a 404 Not Found error is not a permanent problem. You can resolve it using the following methods:

1. Clear Your Browser’s Cache and History

The first way to fix the 404 Not Found error is to clear your browser’s cache and history to improve browser performance. The cache contains all the information from websites you’ve previously visited. It needs to be cleared because it may store numerous web pages that are no longer accessible. These inaccessible pages are often the cause of the 404 Not Found error. Of course, in addition to the cache, your browsing history should also be cleared.

2. Refresh or Reload the Page

The second method—and one of the easiest to perform—is to try reloading the page. This simple step can be the first thing you do to resolve the 404 Not Found error. Additionally, when refreshing, you can press the F5 key on your keyboard. After all, the 404 Not Found error might appear without any significant underlying issue.

3. Check the URL Spelling

Another way to resolve the 404 Not Found issue is to double-check the URL spelling. While this problem may seem trivial, it can affect access to a website. This also indicates that a 404 Not Found error can appear due to a minor issue that can be easily resolved.

4. Update the Website’s Permalink

Next, the 404 error might appear in the website’s permalink. Typically, this issue arises when you migrate a website. Therefore, regularly check and update the permalink to ensure it remains accessible.

5. Update the .htaccess File

In some cases, a 404 Not Found error can also prevent you from accessing the website dashboard. This can certainly make it difficult to reset the permalinks. In this situation, you can resolve it by updating the .htaccess file on your hosting provider.

6. Deactivate Themes and Plugins

The final method to resolve the 404 Not Found issue is to deactivate themes and plugins, as they can affect the website’s URL structure. If the website returns to normal after deactivating a plugin or theme, you can use the default settings to restore the plugin to its original state.

That concludes the explanation of what a 404 Not Found error is and how to resolve it. Generally, the 404 Not Found error does not arise from issues that are difficult to resolve. However, its appearance can still disrupt user activity online. Therefore, to prevent this from happening, ensure you use the domain and hosting that are right for optimizing your website.
