Dropbox option worked fine for me. It complained that it couldn’t complete because of two-stage security, but I knew I didn’t have two-stage enabled. After about 45 seconds the small files popped up and eventually the big zip file finished, too.
Haven’t tried the FTP option, but I actually prefer using Dropbox.
Ok, I lucked out. Tried Site ID = 2 and the domain name I wanted. it seems to work to present the right name to the browser, but I am still not arriving correctly at the site from the start. I get a simple pageok message.
