The most common fix for WordPress 404 errors is to re-save your permalinks: go to Settings → Permalinks and click Save Changes, which rewrites the .htaccess rules. If that doesn't work, check the .htaccess file, deactivate conflicting plugins, and add redirects for moved pages.
Re-save permalinks
Settings → Permalinks → Save Changes regenerates the rewrite rules and fixes most 404s without changing any settings.
Check the .htaccess file
Ensure your .htaccess contains the standard WordPress rewrite block. If it's missing or corrupted, restore the default rules.
Rule out plugins and themes
Deactivate plugins one by one (or switch to a default theme) to find a conflict causing the 404, then update or replace the culprit.
Redirect moved or deleted pages
If a page genuinely moved, add a 301 redirect from the old URL to the new one so visitors and Google reach the right place - this also protects your SEO.
