If you are experiencing an issue where your landing page background image is covered with a white overlay – this could be caused by your WordPress theme adding some custom styling to all pages on your site which will override the background and hide it from view
To fix this, in the LiveEditor, go to Page Settings (on the left menu) > Other Scripts and select “Custom CSS” from the dropdown
Now enter the following code in the box:
body.custom-background{background:none !important;}
Once you save this and refresh the page you should see your background is visible again
