Just upgraded WP 2.9.2 to WP 3.0. With the E-Junkie "add to cart" and "view cart" code in place, the page content flashes for a half second then the browser displays a blank page. But I was able to view the source.
This problem only exhibits in Chrome (5.0.375.86) and Safari 5 (5533.16). FF and IE are okay. The page is here: usdaden.com/shop.
Anybody can help?
