Hmm - In some cases, like if a Web site is using advanced programming techniques, I could see where a site like that site wouldn't display correctly, though even then someone would be able to access it. But that NB page is pretty basic, so I wouldn't think it should matter what version of Chrome anyone uses - at the very least someone should still be able to get through to it.
Try accessing it again. If you get the same message, something very strange is happening...
