I also use a localhost normally, but with PowerCMS it is so much easier to start with a remote database.
It is possible at the hosting company I use, see attached image.
So as you can see, the remote CMS database content is available in the local dreamweaver website. Only, it looks like PowerCMS is looking for a localhost by default while there is only a remote database. D:\xampp\htdocs, is the location of phpadmin local.
