I get directory listing instead of the website index.php

Ubuntu 20.04, Apache 2.4, PHP5.6

I have website with the following vhost config

<VirtualHost *:80>
      ServerAdmin [email protected]
      ServerName website.com
      ServerAlias www.website.com
      DocumentRoot /var/www/html/site_admin/public_html
      # Directory path where code exists
        <Directory /var/www/html/site_admin/public_html>
                Options -Indexes +FollowSymLinks +MultiViews
                DirectoryIndex index.php
                AllowOverride None
                Order allow,deny
                allow from all
        </Directory>
        ErrorLog ${APACHE_LOG_DIR}/website.com-error.log
        # Possible values include: debug, info, notice, warn, error, crit,
        # alert, emerg.
        LogLevel error
        CustomLog ${APACHE_LOG_DIR}/website.com.log combined
</VirtualHost>

.htaccess is disabled

/etc/apache2/apache2.conf has the following Directory module

<Directory />
        Options Indexes FollowSymLinks
        AllowOverride None
        Require all denied
</Directory>

<Directory /usr/share>
        Options Indexes FollowSymLinks
        AllowOverride None
        Require all granted
</Directory>

<Directory /var/www>
        Options Indexes FollowSymLinks
        AllowOverride All
        Require all granted
</Directory>

This is the website directory:

When I try to browse the website at https://website.com, I get

instead of the actual website

Please advise

Is php installed? What does php.info give you? Also It seems all files have full 777 permission which a security risk.

I figured the issue. In my /etc/apache2/apache2.conf, at the end, I had

# Include the virtual host configurations:
IncludeOptional /mnt/efs/fs1/sites-enabled/*.conf

This was due to Apache2 non-default root directory multiple websites 403 forbidden configuration

Once I changed this part to

# Include the virtual host configurations:
IncludeOptional sites-enabled/*.conf

The site started working

Thanks
