body background image not loading

Hi,
I had added a background image to my body and it was working perfectly. It suddenly turned white and I can’t see what I’ve done. My site is https://www.lacostita.com and the code I’m using is:

Now I have a new problem though, suddenly the body background, which I have set to a tiled image which was working perfectly has turned white. This is the code I’m using:

body {
font-size: 14px;
font-size: 1rem;
font-family: Helvetica, Arial, sans-serif;
text-rendering: optimizeLegibility;
background: url(“https://lacostita.com/wp-content/uploads/2013/06/tile.jpg”);
}
any ideas what could be going wrong?

Thanks.
