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 restart
in order to allow the changes to take effect. Please inform if you succeed.
