Change background image on master page

I currently have no image as my background.  I have added an image as a background.  however, when I bring up a child page the image flashes and then turns white.  If I attach a new child page to the master page it works fine.  How do I get the image to show on an old existing master/child page? 


Any chance the background of your child page is white?

I did look at that.  I have tried both not set and transparent color. However, if I set up a new test page as a child to the parent and copy in the sections it works.  It seems like it is stuck in the format it was in and cannot be changed.   I was trying to not have to recreate all the child pages.
