I made a gallery with 4 images, then went to the widgets panel, dragged the NextGEN Media RSS widget into my sidebar, gave it a title, saved, went to look at my site, and there's nothing new in the sidebar.
Then I went back to the widgets page and the Media RSS widget is gone. Like I never did anything.
Do I have to write out an XML file? Did I need to do something to the images when I uploaded them? I didn't put any tags on them or any alt text, maybe something to do with that?
Anyone know how I messed up? Or is my install of NextGEN messed up?
This is on a test site, with NO other plugins, and the DEFAULT theme, and no edits to ANYTHING.
