I am using Graphene 1.6.2 on http://www.cartersgymnastics.org/ and usually viewing in the latest Chrome version. When the site first comes up to the home page in Chrome and IE, it displays the full width of the screen and with the side column at the bottom, instead of a two-column format. All of the rest of the pages and posts display correctly, and the home page does as well if you navigate to another page and then click back to the home page. At the host, the site is set to point to http://www.cartersgymnastics.org/wordpress. I have made no editing or other changes to any templates, since I do not have any experience doing so. The problem seemed just to appear (as in not after an update) out of the blue.
