What does 404 error mean and what causes it?

When a 404 error message pops up, it simply means the server can’t find the file the user requests.

For instance, If you try accessing a specific URL (say domain.com/what-is-WordPress), if no content carries that name, you’ll get a 404 error message.

This error has absolutely nothing to do with your server, it just means the requested file (image, page, or post) is missing.

The error message may differ slightly based on the browser you use.

Google Chrome reads “404. That’s an error.” “The requested URL /~ was not found on this server. That’s all we know”

Other variations include:

• “The page cannot be found”
• “We can’t find the page you’re looking for.”
• “The requested URL was not found on this server.”
• “Not Found”
• “HTTP Error 404”
• “Error 404”
• “404 Not Found”

Also, you can set up your own unique 404 error page using a WordPress plugin. While this isn’t crucial, it helps you explain better to your audience, letting them know what next to do.

Note that this error is not unique to WordPress alone. It can happen on any website.

How to Fix WordPress Posts Returning 404 Error

Since this ‘404 not found error’ indicates a problem with your links, you can usually fix it by ensuring your permalinks are correctly configured and saved. You may also need to reset your linking structure using your .htaccess file.

1. Save Permalinks to Fix WordPress Error 404

Very often, the solution to 404 error in WordPress is simply saving your permalinks. Doing this will update your .htaccess file with the correct configurations for your WordPress website.

To save permalinks, login to your WordPress dashboard and go to Settings > Permalinks.

Next, scroll to the bottom and simply click Save Changes.

If saving the permalinks does not solve your WordPress error 404 issue, you can manually reset it by editing your .htaccess file.

To do this, access your website files using FTP. When connected via FTP, locate your .htaccess file and edit it.

Add in one of the following codes, save, and upload the updated file to your server:

A) Reset permalinks when your site is in the main domain

If your site is on the main domain, e.g. www.yoursite.com, add this code to your .htaccess file:


# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress


After editing and uploading the file, refresh your site and access posts and pages to see if this fixes your WordPress error 404 issue.

B) Reset permalinks if your site is in a subdomain and fix WordPress 404 Error

If your site is installed in a subdomain, such as blog.yoursite.com, use this code instead.


RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteRule ^wp-admin$ wp-admin/ [R=301,L]
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule ^(wp-(content|admin|includes).*) $1 [L]
RewriteRule ^(.*\.php)$ $1 [L]
RewriteRule . index.php [L]


C) Reset permalinks when your site is in a subdirectory

If your site is on a subdirectory, such as www.yoursite.com/blog, edit .htaccess to include this code instead.


RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?wp-admin$ $1wp-admin/ [R=301,L]
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(wp-(content|admin|includes).*) $2 [L]
