Solved: permission denied for PHP container to read stream

[HugoFara]

In rare cases, after installing the PHP container with Docker, you can run into the issue PHP Warning: require_once(inc/session_utility.php): Failed to open stream: Permission denied in /var/www/html/index.php on line 72. LWT will then crash.

To solve it you need to add reading permission for /var/www/html to the www-data user. Steps:

1. Get the guid of the user running cat /etc/passwd or cat /etc/passwd | grep www-data.
2. Add permissions chown -R {gui}:{gui} /var/www/html.

TADAAA! Things may run smooth now!
