Users on my domain cannot use Sites
I've just set up Mailhosting for my domain. I have enabled all the apps for the first user, and he can use Docs, Sheet, Writer, Creator, but not Sites. Sites appears in his Apps drop-down menu, but he gets a message saying:
Access denied, Insufficient privileges to create a site. Contact account administrator.
But I can't see an entry for Sites in the list of apps to enable. Where is this please? I've checked that I can use Sites myself.
