I just switched from Duster to the new Twenty Eleven theme. For some reason I set a featured image for a post, make it a sticky, and the image is not showing up on featured area. It’s completely blank.
The sourcecode of “Ice Cream Summer Lovin” shows no trace of a featured image. Perhaps you forgot to click Update after clicking “Set as featured image”? Check the post editor and see if the image shows up in the Featured Image module.
Now I’m seeing a closeup of an icecream with pecans for the first sticky and a closeup with raspberries for the other. If you’re not seeing them, try clearing your browser’s cache. (What browser and version are you using?)
