Response from the site administrator

Sorry this had to be disabled for now. DropBox changed how the sharing links work and the library I use for DropBox doesn't support it. I am looking at upgrading it to support that again.
However there are workarounds for you. The dropbox website and mobile website provide the links you need. As for DropBox on the phone, I use "BoxFiles for Dropbox" which has a free version. That's probably the easiest way.
Sorry for the inconvenience!
