So whenever I try to change the CSS code for the background image, I modify it and nothing changes. It's still the same background image for the theme that I've selected(The light theme in this case)
Here is the line of code that I've got for it:body
{
    background-image: url(https://hobbyistworld.createaforum.com/styles/hobbyistworld/files/3061_BG.png) repeat-x;
}

It didnt work. 

I managed to get it working now.
