Which background are you talking about exactly? You have a header background which I've already told you exactly how to remove it. Additionally your main teal colored background isn't repeating?
my main teal colored background isn't repeating but when you do alot of CLTR - (big screen) , you will see that the image background will move and take place only on left of screen ... ! . .

like here :

       background-image: url(https://image.noelshack.com/fichiers/2017/03/1485085830-imgpsh-fullsize-3.jpg) !important;
    background-repeat: no-repeat;
    background-attachment: fixed;
#headerMover #headerProxy, #header, #content
    background-color: transparent !important;

i tried to do what you said but didn't work ..

am really sorry about my bad english .. but please is it possible to help me really to fix it cause I am desperate now ... :(
At this point between all your threads I'm not even sure of the issue. You have custom code on the background in the header so you've clearly done it intentionally, what exactly is the problem here?
