WordPress may encounter a 404 error on LiteSpeed servers, especially when the web application is not configured correctly or when sites are migrated from different servers such as NGINX or APACHE.
This issue is also common with OpenLiteSpeed servers, which are utilized by many website owners who opt for the free version of the LiteSpeed web server.
The LiteSpeed 404 error occurs on WordPress due to a misconfiguration of the .htaccess file after creating a new website or migrating from a different web server.
To resolve this error, you need to edit the .htaccess file located in the WordPress root directory. Sometimes, web servers hide this file for security reasons, so you may need to enable access to hidden files or contact your web service provider for assistance.
If you have access to the .htaccess file, you can edit and overwrite the existing one with the following code:”
RewriteBase /
RewriteRule ^/index.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
Then save it, done.
This is the method we use to resolve the LiteSpeed 404 error, which prevents access to either the entire website or certain pages after the creation of a new website or migration.
