Why do many pages give a 404 error after turning on the CNC?

Question

Apache HTTP Server

The WP site now has CNC enabled. Why do many pages give a 404 error after turning on the CNC?
This is what .htaccess looks like:

# 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

Bitnami Wordpress, AWS, Ubuntu

Answer 1

That's it, I fixed this problem, the CNC broke the code in the theme's functions.php file!

Answer 2

check if mod_rewrite apache module is installed
