Call me crazy..
But I am using the default theme but modifying it pretty extensively.

And sadly I am new to the way C5 still works and in the main.css stylesheet I added a background image, put that in the themes images folder, and when I inspect I can see the background-repeat property but for the life of me the image won't show up.
The path is set correctly, but I feel something is overriding it.
I also created a 'new' images folder in the them and set the path to that with no luck.

Any thoughts?
I can alter background-color til the cows come home but the background-image won't take.

Thanks to all
