Fix WordPress with All Pages Returning 404 Not Found

Problem

I encountered a strange issue with WordPress: while the homepage loaded properly, all the other pages failed to do so. Instead, an error page displayed the message:

Not Found

The requested URL was not found on this server.

However, since I had migrated the files from another server, all the pages should already exist. I suspected that the .htaccess file might be the culprit, but after hours of troubleshooting, I still had no clue.

Solution

As it turns out, in my case, the .htaccess file was correctly configured. The issue lay elsewhere. To resolve it, edit the httpd.conf file:

    sudo vi /etc/httpd/conf/httpd.conf

Locate the section that starts with:

    <Directory "/var/www/html">

Change the configuration from AllowOverride None to:

    AllowOverride All

Finally, restart the server:

    sudo systemctl restart httpd

After doing this, all the pages should render properly.
