Set the perfect permissions for WordPress:

cd /path/to/wp/webroot; find . -type d -print0|xargs -0 chmod 755; find . -type f -print0|xargs -0 chmod 644; chown nginx:nginx * -R

*Update nginx:nginx to your web daemon user and group

Recently had an issue where I was unable to upload media within WordPress. Turned out the user and group in php-fpm’s www.conf was incorrect. To fix:

vim /etc/php-fpm.d/www.conf

user: nginx
group: nginx

Restart php-fpm

service php-fpm restart
