I had this problem in every host i tried to install nopcommerce. They all allow me to change permissions on files and sub-folders but not on root folder. Do we realy need modify permissions to root folder? Isn't it enough all the other permissions described on the manual?
you don't have to modify permissions on root folder if you install nopcommerce manually without the installer. If you want to configure google checkout then you need to modify permissions on web.config or you can write the values there manually
