DropBox Web Server Resync Site

Recently, I described a way to serve exam view test pages from a DropBox web server. Since then, several teachers have had trouble with pages or tests they have uploaded not being served by the droppages (Drop Box) web server. The server responds with a 404 file or page not found. The issue is easily corrected by going to my.droppages.com and selecting the reset sync button on the page used to manage your web site. Wait a few minutes, then refresh the  troublesome exam view test or page.
