Hi David. Works for me in all BP child themes. I presume you cleared cache/cookies and are targetting the correct selector , so

:

1. If there is !important after the background image url in parent theme, add it in your declaration in child theme – none !important

2. an alternative: create blank 1×1.gif file and use that for your background url(images/1×1.gif) to override parent theme
