Problems with friendly url apache 2.4.18

Good night, guys, how are you?

I installed apache 2.4.18 on my linux mint 18.1 "Serena" ciannon. When I log in to the system it stays blank and does not load the content.

• I've already activated mod_rewrite

• I've already changed AllowOverride in both apache2.conf and sites-available / 000-default.conf

  <Directory /var/www/html>
          Options -Indexes +FollowSymLinks +MultiViews
          AddType application/x-httpd-php .php
          AllowOverride None
          Require all granted
  </Directory>
  

• The system works perfectly on my web host (hostgator).
• Each new change I give restart in apache in order to validate the changes ...

• On the web server and on the local server the login page loads perfectly and creates the link: system / index.php / auth / login . When I log in, the web server (hostgator) loads the address: mysite.com/system/index.php/ and the system runs, however on the local server it loads the url localhost / system / and does not show the content.

  • I decided to do a test by taking the complete url to register a new patient in the system, www.mysite.com / system / patient / new and put it on the local server and gave the same thing, page is blank ... however it only works and loads the content if I add index.php: system / index.php / patient / new /

I do not know what to do ...

Can this be a problem in the friendly url?

Can anyone help me?
