WordPress Posts Returning 404 After Update Fix
What You Are Experiencing
Do any of these sound familiar?
Your WordPress site is critical, and seeing 404 errors on what should be live content is alarming. Unlike a general WordPress Pages and Posts Showing 404 Error, this specific issue targets your dynamic content archives, often appearing after a recent update or change. This means your blog posts, categories, and paginated results are inaccessible, severely impacting user experience and SEO.
If any of these match, you are in the right place.
Root Cause
Why this happens
This specific 404 error, affecting blog, category, and archive pages, typically stems from a disruption in how WordPress generates its rewrite rules. The most common culprit is a corrupted permalink structure, often triggered by a WordPress core update, a plugin update, or a theme change that conflicts with the existing rewrite rules.
Another frequent cause is an improperly configured or corrupted .htaccess file. This file dictates how your server handles URL requests, and if it's incorrect, WordPress can't correctly route requests for dynamic content like category archives or paginated results. Sometimes, a plugin or theme conflict can also interfere with these rewrite rules, leading to these specific 404s, similar to how WordPress sitemaps or feeds might return 404s.
Less commonly, but still possible, are server-level configuration issues or database inconsistencies where the permalink settings are stored incorrectly, preventing WordPress from resolving these dynamic URLs.
Try This First
Steps you can take right now
Work through these in order. Each step is safe unless noted otherwise.
Flush WordPress Permalinks
This is the most common fix for blog, category, and archive 404s. Go to your WordPress admin dashboard, navigate to Settings > Permalinks. Without changing anything, simply click the Save Changes button. This action forces WordPress to re-generate the .htaccess file and flush its rewrite rules, which often resolves issues where wordpress posts returning 404 after update.
Check and Repair .htaccess File
If flushing permalinks doesn't work, your .htaccess file might be corrupted or misconfigured. Access your site via FTP or your hosting file manager. Locate the .htaccess file in your WordPress root directory. Before making any changes, download a backup copy of this file. Then, delete the existing .htaccess file. Go back to Settings > Permalinks in WordPress and save changes again. WordPress will generate a new, clean .htaccess file. If this fixes the wordpress category pages 404 error, compare the old and new files for differences.
/public_html/.htaccess
Temporarily Disable Plugins and Theme
A plugin or theme conflict can interfere with WordPress's rewrite rules, causing 404s on dynamic pages. Access your site via FTP or file manager. Navigate to wp-content/plugins/ and rename the entire plugins folder to something like plugins_old. This deactivates all plugins. Check if your blog/category pages work. If they do, rename the folder back to plugins and reactivate plugins one by one to find the culprit. Repeat this process for your active theme by renaming its folder in wp-content/themes/ and activating a default theme like Twenty Twenty-Four. Be aware that deactivating plugins can temporarily affect site functionality.

Verify WordPress Address (URL) Settings
Incorrect WordPress Address (URL) or Site Address (URL) settings can lead to widespread 404 errors, including on wordpress tag pages returning 404. In your WordPress admin, go to Settings > General. Ensure that both the 'WordPress Address (URL)' and 'Site Address (URL)' fields are identical and correctly reflect your domain, including https:// if you use SSL. If you recently migrated or changed domains, this is a critical check. For migration-related 404s, see our guide on WordPress 404 After Migration, Domain Change or SSL.
