Hello, I have Penumbra running on two sites, and on one site it's running fine, but on the other site, it is cutting off the bottom half of the background image, no matter whether the background is set to fixed or scrolling. I tried replacing background.png in the /images folder with a transparent .png of the same dimensions but it only came up white rather than dark, still cutting off the bottom half of my background image, so I put it back.
You can see what I mean:
http://goo.gl/kxsyIV <-- where it's running fine - background image tiles all the way to the bottom of the site
http://goo.gl/Kt6eCv <-- where it's cutting off the bottom half of the background image
The background image (which I have flipped both horizontally and vertically so it would tile well) is here - http://goo.gl/zUzxYq
Thank you for any suggestions you might have for how I could do it differently to make it work.
