Do you mean google chrome ? or do you mean google search engine ?
If the former it might be to do with how google chrome caches websites, and it might need clearing, but I don't know how because I don't use it. I'd suggest you open firefox, and chrome, delete your old chrome bookmark, and then copy the firefox url from the address bar, and paste it into the chrome address bar, then bookmark it again, you will probably need to login again in chrome.
If the latter using your google search history, its probably still looking at the old web address, not much we can do about that, but its better to use the bookmark method above to access the site anyway.
