I upload the channel art, adjust the crop, save it, and then it changes from the upload prompt to a white box. If you refresh the page the upload prompt is back. Tried on Chrome.

Make sure the file size is 2MB or less. I had the same problem and this fixed it. They should make sure there is an error that says file is too large so you know.
