Widget in Sidebar does not display tweets

I can view my tweets in preview but they won’t display in my sidebar widget, which instead reads “No result could be fetched.”

The width and height of the output are both set to 100%. Profile image size is set to 48 pixels.

It seems like a cool plug-in. I’d love to get it to work.

Thanks!
