Hello!
I'm posting here because I can't find a better section for my question.
Now: I've Magento 2.1.7 , and in the home of my admin section, I see this error:
"Your web server is configured incorrectly and allows unauthorized access to sensitive files. Please contact your hosting provider."
How I can see what files/directory has wrong permissions?
Thank you!
You need to check Magento links for a gives to permission,

Sounds like you have file permissions issues. Running these lines should fix the permissions:
cd <your Magento install dir> find var vendor pub/static pub/media app/etc -type f -exec chmod u+w {} \; find var vendor pub/static pub/media app/etc -type d -exec chmod u+w {} \; chmod u+x bin/magento
chown -R www-data:www-data <your Magento installation>Replacing www-data with that user account (apache, www, nginx, etc).
