TL;DR: To fix the 404 Not Found error in WordPress, first ensure your Permalink Settings are correctly configured and then regenerate your .htaccess file by saving the settings twice. If the issue persists, check for plugin conflicts or server configuration issues that may be blocking proper URL routing.
Understanding the 404 Error
A 404 error indicates that the server cannot find the requested resource. In WordPress, this is almost always caused by incorrect permalink structures or a missing or corrupted .htaccess file. When you change your URL structure, WordPress needs to rewrite URLs to match the new format. If this rewrite rule fails, visitors see a broken page. This guide will walk you through the most common and effective solutions to restore normal functionality to your site.

Step-by-Step Fix
Step 1: Reset Permalink Settings
This is the most effective first step. Log into your WordPress admin dashboard and navigate to Settings > Permalinks. Do not change any options. Simply click the Save Changes button at the bottom of the page. This action forces WordPress to flush the rewrite rules and regenerate the .htaccess file. Often, this simple action resolves the issue immediately.
Step 2: Check .htaccess File Permissions
If resetting permalinks does not work, your .htaccess file might be read-only or missing. Access your server via FTP or your hosting file manager. Look for the .htaccess file in the root directory. Ensure it contains the standard WordPress rewrite rules. If it is empty, try deleting it and repeating Step 1, allowing WordPress to create a fresh file. Ensure the file permissions are set to 644 for security and accessibility.
Step 3: Disable Plugin Conflicts
Sometimes, caching or SEO plugins interfere with URL rewriting. Deactivate all plugins temporarily. Check if the 404 error is resolved. If it is, reactivate plugins one by one to identify the culprit. Common offenders include aggressive caching plugins or misconfigured security suites. Once identified, update or replace the conflicting plugin.
Step 4: Check Server Configuration
For Apache servers, ensure that AllowOverride is set to All in your server configuration. For Nginx, verify that the server block includes the correct try_files directive. Consult your hosting provider if you are unsure about these technical settings, as incorrect configurations can persistently block proper routing.
FAQ
Q: Why does the 404 error appear only on specific posts?
A: This usually indicates that the specific post has a corrupted slug or a broken internal link structure. Check the post editor for unusual characters in the URL slug and update the permalinks to refresh the routing table.
Q: Can a caching plugin cause a 404 error?
A: Yes, caching plugins sometimes serve outdated or cached versions of deleted pages. Clear your site cache and browser cache completely. If the issue continues, consider disabling the caching plugin temporarily to rule it out as the source.
Q: What if I cannot access the WordPress admin dashboard?
A: If you are locked out, connect via FTP or SFTP. Manually edit the .htaccess file to include the standard WordPress rewrite rules. Alternatively, rename the plugins folder via FTP to deactivate all plugins, which may restore access to the dashboard.
