I played around with the preview tabs for the custom design package and it worked fine. But after I purchased it last night, it stopped working. When I click on customize on the drop down menu, my blog page comes up, the customization sidebar appears on the left of the screen - and then my page disappears; all that remains is the black background. I've emptied my cache, closed and reopened Safari, refreshed the page countless times. I can change the background color, but that's ALL I see. A big blank page in another color. Help would be much appreciated.
The blog I need help with is 52at52.net.
