Hello, I'm new using DigitalOcean I created a Droplets with Ubuntu 14.04, I followed the instructions in the Initial Server Setup, create a new user, change the SSH port, etc., I followed the tutorial for LAMP Stack on Ubuntu 14.04, I have installed Apache2, MySQL, PHP, Secure phpMyAdmin installation, configure the host to run through a domain (Setup Host Name), install WordPress; Postfix, ProFTPd for file transfer over SSH (sftp). When I was installing a Wordpress theme, I requested for details SSH keys, searching Google I found that assigning changing the public_html owner from my user to www-data, wordpress works fine! sudo chown www-data:www-data -R /var/www/html, the theme was installed without problems, I work several days without errors, until I tried the sftp via ssh. Using the sftp I had access to my user's folder but when I went to /var/www/html, there is not files or cannot see them, I realized that changing the permissions to www -data, my user did not have access to them, so I change the owner of the files to my new user, not root, I assign the chown to the new user created in the initial server setup. The page began to launch a 403 Forbidden. I put back chown to www-data on folder /var/www/ and now I see the index.php (Default page) but can’t navigate or see any post or subfolder, the server say: 403 " You do not have permission to access on this server xxxx." Any help?
