How to Fix 404 Errors on Your WordPress Site

Broken pages cost you more than a bad visitor experience. Knowing how to fix 404 error problems on your WordPress site protects your search rankings, keeps your backlink equity intact, and stops Googlebot from wasting its crawl budget on dead URLs.

What Is a 404 Error and Why Does WordPress Show It

A 404 error is the HTTP status code a server returns when it cannot find the page a visitor requested. ( [no URL provided in metas]) Your browser sends a request, the server looks for the page, and when it comes up empty, it sends back the 404 response. That exchange happens in milliseconds, but the consequences for your site can last much longer.

Two types of 404 responses exist. A hard 404 means the server returns the actual 404 HTTP status code. A soft 404 means the server returns a 200 OK code, which signals success, but the page content tells the visitor that nothing was found. Soft 404s cause specific problems for search engines because they appear to be live pages even though they carry no real content.

WordPress handles URLs differently than most platforms. It builds every URL from your permalink settings, and those settings connect each post, page, and archive to a specific address. When that connection breaks, a 404 is the result.

Common Causes of 404 Errors on WordPress Sites

Common causes of 404 errors on WordPress sites include permalink structure changes, deleted content, and plugin conflicts. A permalink structure change is the most disruptive. When you switch from one URL format to another, every existing URL on your site can break at once because WordPress no longer knows how to match the old addresses to your content.

Other frequent causes include:

• Deleted or unpublished posts and pages. Trashing a post without a redirect leaves every link pointing to it with nowhere to go.
• Mistyped or broken internal links. One wrong character in a URL creates a dead end for visitors and crawlers.
• Plugin or theme conflicts. Plugins that register custom URL patterns stop working when those plugins are removed or replaced, leaving their URLs unresolved.
• Domain migrations and site moves. Moving to a new domain without mapping old URLs to new ones breaks the entire site at once.
• Renamed or moved media files. Any page that references an image or file by its old path returns a broken reference after the file moves.

These causes are common across sites of every size. They tend to build up gradually, which is why regular audits matter more than one-time fixes.

How to Fix 404 Errors in WordPress Step by Step

The fix 404 error WordPress process follows a clear order: start simple, then escalate. ( [no URL provided in metas]) Most errors resolve at the first step. You only need the advanced methods when something deeper is wrong.

Start With the Permalink Settings Fix

Flush your permalink settings first. In your WordPress dashboard, go to Settings, then click Permalinks. Do not change any settings. Just click Save Changes at the bottom.

This forces WordPress to rebuild its rewrite rules. Those rules are the internal map WordPress uses to connect each URL to the right piece of content. When the map gets corrupted, WordPress can't route visitors correctly, and 404s appear. Saving the Permalinks page regenerates the map without changing any of your actual URL settings.

This fix works for most 404 errors caused by permalink changes, plugin conflicts, and certain server migrations. It takes under a minute and requires no plugins or server access.

Setting Up 301 Redirects and Editing .htaccess

When the permalink flush doesn't work, your next step depends on what caused the 404.

If the page was deleted or moved, set up a 301 redirect using a redirect plugin. A 301 redirect tells browsers and search engines that the old URL has permanently moved. You enter the old path and the new destination, save the rule, and the redirect is live immediately. This also passes link equity from the old URL to the new one, which matters if the old page had backlinks.

If you're comfortable in server files, you can write redirect rules directly in your .htaccess file. This file lives in your WordPress root directory and controls how your server handles requests. A basic rule looks like this:

Redirect 301 /old-page/ https://yoursite.com/new-page/

Back up the file before editing it. A syntax error can take your site offline.

If the 404 appeared after a caching plugin update, clear your site cache. Caching plugins can serve a stored 404 response even after the real issue is fixed. Clearing the cache forces fresh responses for every request.

If content was deleted by mistake, restore it from a backup or republish it. Once the page is live at its original URL, the 404 clears without any redirect needed.

If nothing else works, contact your hosting provider. Server-level issues like incorrect directory permissions or a misconfigured virtual host require access that only your host can provide.

How 404 Errors Affect SEO and How to Prevent Them

The 404 errors SEO impact depends on what was on the page before it broke. A 404 on a page with no traffic and no backlinks does little damage. Google drops it from the index after a few crawls and moves on. The real problem is a 404 on a page that earned backlinks, ranked for search terms, or received regular traffic.

When a page with backlinks returns a 404, the link equity from those backlinks stops flowing to your site. ( [no URL provided in metas]) That equity doesn't redistribute to other pages. It's gone. A site that accumulates many broken high-value URLs loses ranking strength over time in ways that are slow to recover.

Googlebot also works within a crawl budget for every site. It only crawls a set number of pages per visit. If many of those pages return 404s, Googlebot spends less time on your live content. For larger sites, this delays the indexing of new posts and pages.

Google Search Console 404 data makes this visible. The Coverage report shows every URL that returned a 404 during recent crawls. Setting up email alerts in Search Console means you'll hear about crawl error spikes right away, not weeks after they started.

One more distinction matters here: a 404 means the page wasn't found but could return, while a 410 status code tells search engines the page is permanently gone. A 410 prompts Googlebot to stop recrawling the URL faster than a 404 does. If you've removed content with no replacement planned, returning a 410 is the more efficient choice.

How to Prevent 404 Errors Before They Happen

Prevention starts before you change anything. Before restructuring your permalink format, export your full URL list and map every old URL to its new destination. Load those redirects into a plugin before you flip the switch. Visitors and crawlers that arrive at old URLs get sent to the right place automatically.

During site migrations, keep a URL change log. Write down every URL that changes, every page that moves, and every post you delete. That log becomes your redirect map and your reference if 404s appear after the migration.

Run a link monitoring plugin on a regular schedule. These tools crawl your site internally, the same way Googlebot does, and flag broken internal links before they turn into crawl issues. Set up alerts in Google Search Console as a second layer so you catch any 404 spikes early.

The Bottom Line

Most WordPress 404 errors come from the same handful of causes: a permalink change, a deleted post, a plugin conflict, or a site migration without redirects. The fix almost always starts with a single click in your Permalinks settings. When that's not enough, the escalation path is clear: redirect plugins, .htaccess rules, cache clearing, and your hosting provider. Prevention is the real win. A redirect plan before any URL change, combined with regular monitoring through Google Search Console, stops most 404s before they affect your rankings.

FAQs

What causes a 404 error on a WordPress site?

A 404 error on a WordPress site most often results from a changed permalink structure, a deleted post or page, a broken internal link, or a plugin conflict that alters how URLs are resolved. Domain migrations without redirect mapping also produce 404s across an entire site at once.

How do I fix a 404 error without using a plugin?

Go to Settings, then Permalinks in your WordPress dashboard, and click Save Changes without modifying anything. This flushes the rewrite rules and resolves most 404 errors. For more specific cases, you can add a redirect rule directly to your .htaccess file.

Is a 404 error bad for SEO?

A 404 on a page with no traffic or backlinks has minimal SEO impact. A 404 on a page with inbound backlinks cuts off the link equity those backlinks carry. Repeated 404s also waste crawl budget that Googlebot could spend on live content.

What is the difference between a 404 and a 410 status code?

A 404 tells search engines the page was not found but may return. A 410 tells search engines the page is permanently gone. For content you've removed with no replacement, a 410 prompts Googlebot to stop recrawling the URL faster than a standard 404 does.

How do I find all the 404 errors on my WordPress site?

Google Search Console is the most accessible starting point. The Coverage report lists URLs that returned 404 responses during recent crawls. You can also install a link checking plugin that crawls your site internally and flags broken links across posts, pages, and navigation menus.
