Hi. I've noticed a lot of people post with this issue and there seems to be different solutions. I tried one, which had me include the following code into the Custom Stylesheet field
margin: 0 auto;
All this did, was make the header section of my site a little wider, which looked awkward, but it didn't fix the background issue and cause it to link. Any suggestions would be greatly appreciated!
The site in question is here. Thanks!
