Background Image Error

I’m currently working on two sites with the same template – NatureFox.
I was able to switch the background image in the first site – but in the other I can not get it show up. I have tried everything.

I cleared my cache… I also hit ctrl F5 per advice I read in another thread.

I compared the 2 style sheets with a text comparison program and the only difference is the actual image link.

I also tried to change the background to a solid color and it won’t work.

When I used google chrome to inspect the element, it has an “!” in a yellow triangle and a slash thru the background color code. I have since changed the color code… so it seems super odd to me.

the url is dev.wcapalms.com

Any advice is greatly appreciated.
Thank you!
