I'm running ubuntu server and have apache installed as a web server. I'm letting my web developers upload files through sftp (ssh) to /var/www. I'm using www-data group to control access to /var/www folder. They are able to upload the files successfully but when they try to access that file in a browser, they get a 403 forbidden error.
How do I make sure that when the files are uploaded, the permissions are set right?
