Blank page after local install (edit: solved)


Installed apache2, php7.0 on debian distro
also installed almost all the required php modules, couldn’t find only ctype
localhost/grav-skeleton/phpinfo.php loads fine, but localhost/grav-skeleton shows only a blank page?
I’m a newbie to linux so don’t understand much about permissions, running
ps aux | grep -v root | grep apache | cut -d\ -f1 | sort | uniq


as a result, and running
ls -l /var/www/html/grav-skeleton
lists everything inside grav-skeleton as

myuser myuser

EDIT: SOLVED adding user www-data as owner of the grav directory:
sudo chown -R www-data:myuser /var/www/html/grav
