Background not appearing

Hi there,

I have been using your plug in as I am building my website. Its fantactic! But it doesnt seem to work with one of my pages. There must be a conflict with my theme or something as the only page that doest work is the blog page.

https://www.stuartjnelson.com/partners/

I cant get a background on this page.

Cheers,

Stuart ??
