I have for a long time had my own website and server using nginx sofware. I have only one page and use (gksudo gedit /var/www/nginx-default/index.html) to make changes to the site with no problems until I wanted to change the email address. I delete the old address then type in the new one then save but it remains the same, I also have deleted the old one then saved then typed in the new one and saved again but nothing. I have deleted and left it deleted then save but it still shows the old address. I am using ubuntu 12.4 LTS. Thanks for any replies
