New install of your plugin on a new custom developed theme with <body <?php body_class(); ?>> in header. Latest version of WordPress. No other plugins are activated. Every background manager configuration I try through the administration of the plugin settings, same result: white background with no background images.
The preview area for the plugin settings shows the background/s. I have dug through the forum to search for a solution.
I am stumped, can you offer some guidance? Your plugin looks to be fantastic and I really want to use it.
