Yeah, you installed it while viewing it on localhost. It auto-detected the URL, and now b2evo thinks that its home is http://localhost/blogs.
Drop all the tables, and then go to http://whw.gotdns.com/blogs/install (the public address) and install from that address, and it'll be fine.
Alternately, you could open up the /conf/ folder instead, and edit the files in there to make sure that they point at the right URL.
Remember to delete the install folder when you're done!
