404 errors can be a real bummer for both website owners and users. They can negatively impact user experience and SEO.
In this article, we’ll dive deep into how to fix a 404 error in WordPress and help you keep your website running smoothly.
Identifying the Causes of 404 Errors
Broken Links and Incorrect URLs
One of the most common causes of 404 errors is broken links or incorrect URLs. These can happen when you accidentally misspell a URL, or when a link points to a page that no longer exists.
Permalink Issues
Another cause of 404 errors is permalink issues. WordPress uses a specific permalink structure for generating URLs, and if something goes wrong, you might end up with a bunch of 404 errors on your site.
Deleted or Moved Content
When you delete or move a page on your site without properly redirecting it, users trying to access the old URL will be greeted with a 404 error.
Issues with .htaccess File
The .htaccess file is a configuration file used by the Apache web server to manage various settings. If it gets corrupted or misconfigured, it can lead to 404 errors.
Plugin Conflicts
Sometimes, plugins can cause conflicts and result in 404 errors. This can happen when two plugins interfere with each other or when a plugin isn’t compatible with your WordPress version or theme.
Resolving Broken Links and Incorrect URLs
Manual Link Checking
Start by manually checking the links on your site. Go through your posts, pages, and menus, and make sure all the links are working as intended.
Using Online Tools and Plugins for Link Checking
Several online tools and WordPress plugins can help you identify broken links. Some popular ones include:
- Broken Link Checker (WordPress plugin)
- Screaming Frog SEO Spider (desktop application)
- Broken Link Checker by Ahrefs
Correcting Broken Links and Updating URLs
Once you’ve identified the broken links, update them with the correct URLs. Make sure to double-check the links after updating to ensure they’re working correctly.
Fixing Permalink Issues
Understanding WordPress Permalink Structures
WordPress allows you to choose from various permalink structures, like “Plain,” “Day and Name,” “Month and Name,” “Numeric,” “Post Name,” and “Custom Structure.” Each structure has its own unique format for URLs.
Refreshing Permalinks in WordPress Settings
To fix permalink-related 404 errors, go to your WordPress dashboard, click on “Settings,” and then “Permalinks.” Simply click the “Save Changes” button to refresh your permalinks. This often resolves the issue.
Customizing Permalink Settings to Prevent Future Errors
To prevent future 404 errors due to permalink issues, consider customizing your permalink structure. Choose a structure that works best for your site and ensures that your URLs are easily understandable and SEO-friendly.
Handling Deleted or Moved Content
Properly Redirecting Deleted or Moved Pages
When you delete or move a page, it’s crucial to redirect the old URL to a new location. You can use a plugin like “Redirection” to set up 301 redirects, which inform search engines that the content has moved permanently.
Creating Custom 404 Pages to Improve User Experience
A custom 404 page can help improve user experience by guiding users to other relevant content on your site. You can create a custom 404 page by editing your theme’s “404.php” file or using a plugin like “404page.”
Resolving .htaccess File Issues
Locating and Accessing the .htaccess File
The .htaccess file is usually located in the root folder of your WordPress installation. You can access it through your hosting account’s file manager or an FTP client like FileZilla.
Restoring the Default WordPress .htaccess File
If your .htaccess file is corrupted or misconfigured, you can restore the default WordPress version. First, back up the current file and then replace it with the following code:
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L] RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L] </IfModule>
# END WordPress
Manually Editing .htaccess for Advanced Troubleshooting
In some cases, you might need to manually edit the .htaccess file to resolve specific issues. This can include adding custom rewrite rules or modifying existing ones.
Be cautious when editing the file, as mistakes can cause your site to malfunction.
Addressing Plugin Conflicts
Identifying Potential Plugin Conflicts
To identify potential plugin conflicts, take note of when the 404 errors started happening. Did you recently install or update a plugin? If so, that could be the culprit.
Disabling and Re-enabling Plugins to Find the Culprit
To find the problematic plugin, disable all plugins and then re-enable them one by one. After enabling each plugin, check your site for 404 errors. Once you identify the plugin causing the issue, you can decide whether to update it, replace it, or remove it entirely.
Resolving Conflicts and Selecting Alternative Plugins
If you’ve identified a plugin conflict, try contacting the plugin’s developer for support. Alternatively, you can look for a different plugin with similar functionality that doesn’t cause conflicts.
Monitoring and Preventing Future 404 Errors
Regularly Monitoring Your Site for Broken Links
To keep your site running smoothly, regularly monitor it for broken links. Use online tools and plugins mentioned earlier to scan your site and identify any issues.
Implementing Best Practices for Link Management
Establish a routine for managing your site’s links. Make sure to update links when you move or delete content, and double-check all new links before publishing them.
Keeping Plugins and Themes Up-to-Date
Ensure that your plugins and themes are always up-to-date. Developers often release updates to fix compatibility issues and bugs, which can help prevent 404 errors.
