Update wordpress file via dreamweaver sftp
I have followed this tutorial https://www.digitalocean.com/community/tutorials/one-click-install-wordpress-on-ubuntu-14-04-with-digitalocean
I can acces to wordpress and it works but I can't update files with dreamweaver. I configure a site and it connect to the server and download files, but when I edit and upload it show me an error.
I have to say that in the tutorial, in the steps that I have to disallow Additional Apache Password Prompt for Admin Areas, I can't safe my changes because it denied and tell me "are you root?"
The same problem if I try to install myphpadmin.
How can I do?
