1. Check the URL – Make sure the URL you are trying to access is correct and matches the intended page or post.
2 Reset Permalinks – Go to your WordPress Dashboard, click “Settings” and then “Permalinks”. Choose any option and click “Save Changes”. This will reset the permalinks and can sometimes fix the 404 error.
3. Disable plugins – If the problem persists, try disabling all your WordPress plugins and then check if the error goes away. If so, re-enable the plugins one by one until you find the culprit plugin that is causing the error.
4. Check the .htaccess file – Check if the .htaccess file in the root directory of your WordPress installation is correct. If it is incorrect or missing, replace it with a new one.
5. Contact your hosting provider – If none of the steps above work, the problem may be with your hosting provider. Contact them to check if there are any server related issues causing the 404 error.
These steps should help you fix the 404 error on your WordPress website.
