When I upgraded this theme on my staging site, the sections of the homepage which use an image as the background are missing the image. (Both sections reference the same image, but one is parallax, while the other is fixed.) If I open up UpFront and save the site, or re-save the permalinks, this has solved the issue.
However, I don't want to have to do this with each update.
Any suggestions on how I can prevent this?
