404 Detective: Keeping Your WordPress Site Error-Free

Have you ever stumbled upon a mysterious error code when browsing your WordPress site? Perhaps you’ve encountered the dreaded 404 error, which can frustrate both you and your visitors. But fear not! As a 404 Detective, I’m here to help you keep your WordPress site error-free and running smoothly.

Understanding the 404 Error

Before we delve into how to prevent and fix 404 errors on your WordPress site, let’s first understand what this error actually means. The 404 error, also known as a “page not found” error, occurs when a user tries to access a page on your site that doesn’t exist or cannot be found. This can happen for a variety of reasons, such as typos in the URL, deleted pages, or broken links.

Causes of 404 Errors

Now that we know what a 404 error is, let’s explore some common causes of this frustrating issue on WordPress sites:

  • Typos in URLs: One of the most common reasons for 404 errors is simply typing in the wrong URL. Make sure to double-check the spelling and format of your URLs to prevent this issue.
  • Deleted or moved pages: If you delete a page or change its URL without setting up a redirect, your visitors may encounter a 404 error when trying to access the old page.
  • Broken links: If you link to external websites or internally within your site, those links may break over time, leading to 404 errors for your visitors.
  • Plugin or theme conflicts: Sometimes, plugins or themes can conflict with each other, causing disruptions in how your site functions and potentially leading to 404 errors.

Preventing 404 Errors

Now that we know what can cause 404 errors on your WordPress site, let’s discuss some tips for preventing them in the first place:

  • Regularly check your site for broken links using a tool like Broken Link Checker. This plugin can automatically scan your site for broken links and notify you so you can fix them promptly.
  • Set up redirects for any deleted or moved pages using a plugin like Redirection. This will ensure that visitors who try to access old URLs are automatically redirected to the appropriate new page.
  • Keep your plugins and themes updated to prevent conflicts that could lead to 404 errors. Regular updates will also ensure that your site is running smoothly and securely.
  • Use a custom 404 error page to provide a more user-friendly experience for visitors who encounter this error. You can create a custom 404 page that includes helpful information and links to other parts of your site.

Fixing 404 Errors

Despite your best efforts, 404 errors may still occur on your WordPress site. Here are some steps you can take to fix these errors and keep your site running smoothly:

  • Check the URL for typos and correct any errors that may be causing the 404 error.
  • Use a plugin like 404 to 301 to automatically redirect users from the incorrect URL to the correct one.
  • If a page has been deleted or moved, set up a redirect using a plugin like Redirection to point visitors to the new page.
  • Monitor your site for 404 errors using a tool like Google Search Console. This will help you identify any recurring issues that need to be addressed.


As a WordPress site owner, keeping your site error-free is essential for providing a positive user experience and maintaining the integrity of your site. By understanding the causes of 404 errors, implementing preventative measures, and knowing how to fix these errors when they occur, you can ensure that your site remains error-free and running smoothly for your visitors.
