Root Cause
Why this happens
A WordPress pages showing 404 error typically indicates a problem with how WordPress generates or interprets its URL rewrite rules. These rules dictate how your site's URLs are mapped to actual content. When this mapping breaks, the server can't find the requested page.
Common culprits include a corrupted .htaccess file, which is crucial for permalinks. An update to WordPress core, a theme, or a plugin can sometimes overwrite or conflict with these rules, leading to a WordPress 404 error after update. This is especially true if the update wasn't fully compatible or introduced a bug.
Issues with how custom post types are registered or how a multisite network handles its subdomains can also cause specific 404s. For instance, if your WordPress custom post type 404 error persists, it often points to an issue in the post type's rewrite arguments or a failure to flush permalinks after registration. Similarly, 404 errors after migration or domain changes are almost always related to outdated URL references or incorrect server configurations.
Try This First
Steps you can take right now
Work through these in order. Each step is safe unless noted otherwise.
Refresh Permalinks
Go to your WordPress admin dashboard, navigate to Settings > Permalinks. Without changing anything, simply click the Save Changes button. This often flushes the rewrite rules and can resolve a WordPress permalinks causing 404 error.
Check .htaccess File
Connect to your server via FTP or file manager. Locate the .htaccess file in your WordPress root directory. Sometimes, this file gets corrupted or has incorrect rules. Rename it to .htaccess_old. Then, go back to Settings > Permalinks in WordPress and save again. This will generate a fresh .htaccess file. If your site works, carefully review the old file for any custom rules you need to re-add. Be cautious: incorrect edits to .htaccess can break your site entirely.
/public_html/.htaccess
Deactivate Plugins
A newly installed or updated plugin can sometimes conflict with WordPress rewrite rules, leading to my WordPress pages are all 404 not found. Deactivate all plugins via FTP by renaming the wp-content/plugins folder to plugins_old. If your site works, rename it back to plugins and reactivate plugins one by one to find the culprit.
/wp-content/plugins
Verify Custom Post Type Registration
If you're experiencing a WordPress custom post type 404 error, ensure your custom post type is registered correctly and its rewrite rules are flushed. This usually involves visiting the Permalinks settings page after registering or modifying a custom post type. Check your theme's functions.php or a custom plugin for the registration code.
Increase PHP Memory Limit
While less common for 404s, insufficient PHP memory can cause unexpected behavior. You can try increasing your PHP memory limit by adding define('WP_MEMORY_LIMIT', '256M'); to your wp-config.php file, just above the /* That's all, stop editing! Happy publishing. */ line.
/wp-config.php
