So I changed it from /var/www to /home/John/Dropbox/www and I also did chmod 755 /home/John/Dropbox/www but it still says You don't have permission to access / on this server.
I forgot how to do this, I guess I need to add the www-data usergroup to the folder...I don't remeber anymore, can you guys help me out.
sudo apache2ctl restartin order to allow the changes to take effect. Please inform if you succeed. – Geppettvs D'Constanzo Nov 06 '13 at 19:12
