I'm created my presentation a long time ago and have a placeholder which displays content from special pages on my website. I had these setup with a Gadget using a URL. Since the free storage is going away, I have moved all my files to my website to store them. As I was updating my presentation, I changed the URLs on my gadget but everything quit working! So I re-did all these URL from scratch.... But now when I try to add "Content by URL" add Gadget and enter my URL, I get the XML Error. So I chanced from Gadget to URL. So that seems to work, but there is also the option to add a Web Page Gadget under "Content" which looks more like what I did before. So the question is: What is the difference???
