1. You have to edit the .htaccess file as below:

DirectoryIndex index.php
RewriteEngine On
Options +FollowSymLinks
Options -Indexes
RewriteCond %{SCRIPT_FILENAME} !-d  RewriteCond %{SCRIPT_FILENAME} !-f
RewriteRule . index.php [L,QSA]

2. You have to edit your apache2.conf file to allow rewrite. Your apace2.conf file is located at /etc/apache2

On the file, find the location on file which says:

<Directory /var/www/>    Options Indexes FollowSymLinks    AllowOverride None    Require all granted
</Directory>

and replace that with:

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

3. You have to enable the rewrite module. In your terminal write:

sudo a2enmod rewrite

Then RESTART apache2 for the changes to commit. The site will then show the internal pages.

sudo service apache2 restart
