I actually lost my custom logo, favicon, and banners when I changed to Sydney yesterday, I just wanted to look and see how it looked instead of custom. The backgrounds reverted to basic, I had to re-work it. It is now better than it was, but still slowly working to get it back. I now need to find out how the postage calculator works in Mobilia without losing the pics again. The product photos stayed, and descriptions...thank goodness, there are hundreds of them!
Oh yes, also lost the posts, won't get to the first post again today!
