When you try to add a background image to website it fails url(/"..//files/background.png") repeat

Yes, adding background image through “page background >> style setting” seems that has some issue. Core development team will be checking into it. In the mean time, you use add background image by adding global css:

body{   
    background:url(https://xxxxxxx.jpg) no-repeat center center fixed;
    -webkit-background-size: cover;
    -moz-background-size: cover;
    -o-background-size: cover;
    background-size: cover;   
}
