Today all of a sudden, my custom background image and custom header image disappeared. Even after reuploading the images through the dashboard using "Header" and "Background" under "Appearance," the custom images I wanted to use wouldn't upload to the site.
I'm running wordpress 3.1 and using the the Twenty Ten theme.
Here's my website. http://ponyshops.com As you can see, the default image is in the header. Curiously, it does still have the custom background color I selected.
Even if I try to choose another default header image, the one with the trees and the road still shows up.
