I've added one virtual host to sites-available. It was showing Index Of... a while ago, then I installed mysql, don't know if it's the reason but after that there was 404, then I changed Directoryto /var/www/html/ and is now showing 403.
I'ver tried chown -R www-data:www-data /var/www with no avail.
Also changed DocumentRoot in 000-defaut.conf to /var/www/html/.
There're never any errors in error.log.
It's a vps and i'm accessing it via ssh
