I have a blog called http://www.dahliakhodur.wordpress.com and I am making the custom background. I test it fine on my laptop and it's fullscreen size, yet when I test it on another laptop the background is small and centered.
I am using the theme Modularity Lite
my uploaded background is sized 1500X705! but it is appearing as a small centered box! Why? please help I would really appreciate it.
The blog I need help with is dahliakhodur.wordpress.com.
