Upfront Not Updating With Changes Made To Background Image

Hello all and hope you are having a great weekend.

I have just installed the Spirit theme on a brand new domain, with a brand new install of WP on it.

When I change the background image, it displays correctly while I am still in the editor. When I save and go to the front end of the site, I see nothing and have a white background.

Any ideas?

Also, when I chose to upload an image, this loaded all the way at the bottom of the page, I thought this was normally a pop up on screen. I had to scroll all the way past the other sections of the home page to choose the image for the top most image on the default home page.

Thanks for any and all suggestions,

Nick
