Few things frustrate users more than clicking a link and landing on a 404 error page. In the world of WordPress, these errors are common—but thankfully, they’re also fixable. Whether you’re running a small blog or managing a business site built with Divi, knowing how to fix WordPress 404 errors is crucial for user experience, SEO, and website credibility.
This guide explores why 404 errors happen, how to fix them efficiently, and why working with the best web agency that can help with a Divi website or a trusted web development UK team can make all the difference.
What Is a 404 Error?
A 404 error occurs when a web page cannot be found on the server. It usually means the URL was entered incorrectly, the page was moved without a redirect, or it was deleted. WordPress, being dynamic, can generate 404s for several reasons—ranging from plugin conflicts to permalink issues.
While a single broken link might seem minor, too many 404 errors can:
Hurt your SEO rankings
Frustrate users and increase bounce rates
Impact your website’s credibility
That’s why it's essential to identify and fix 404 errors quickly.
Common Causes of WordPress 404 Errors
Before diving into solutions, it's helpful to understand the root causes. Here are the most common reasons you’ll see 404 errors in WordPress:
Broken or outdated permalinks
Moved or deleted pages/posts without a redirect
Theme or plugin conflicts (especially with page builders like Divi)
Typos in internal or external links
Changed domain or site structure
Incorrect .htaccess file configurations
How to Fix WordPress 404 Errors
Let’s walk through a practical step-by-step process for resolving 404 errors on your WordPress website.
1. Reset Permalinks
This is the quickest fix and solves most 404 errors due to permalink structure issues.
Go to WordPress Dashboard > Settings > Permalinks
Click “Save Changes” (you don’t need to modify anything)
This regenerates your .htaccess file and often fixes broken links caused by internal routing.
2. Create 301 Redirects
If you’ve changed the URL of a post or page, set up a 301 redirect to forward the old URL to the new one.
Use plugins like Redirection or Yoast SEO Premium
Add manual redirects in your
.htaccessfile (for Apache servers)
Example:
301 redirects are especially useful for SEO, as they preserve link equity.
3. Fix Broken Links
Scan your site regularly for broken internal and external links using tools like:
Screaming Frog
Ahrefs
Broken Link Checker
Once identified, update or redirect the links accordingly.
4. Check for Plugin or Theme Conflicts
Sometimes plugins or themes—particularly advanced builders like Divi—can create 404 issues.
Temporarily switch to a default WordPress theme (like Twenty Twenty-Four)
Deactivate all plugins, then reactivate them one by one to find the conflict
Clear your cache after each change
If the issue appears after enabling Divi, it may require help from the best web agency that can help with a Divi website, especially if custom templates or modules are involved.
5. Restore Missing Pages
If a user gets a 404 error because a page was deleted, consider:
Recreating the page with the same URL
Redirecting to the most relevant existing content
Updating all references to that page across the site
6. Customize Your 404 Page
Even if 404s occur, you can improve the user experience by customizing your error page.
Include:
A helpful message ("Oops, this page doesn’t exist.")
Search functionality
Links to popular or recent content
A contact form
Most Divi users can easily customize the 404 page through the theme builder.
