Did you do your DNS nameserver changes to point your domain to your new host? I assume the domain name is yours! What is happening as near as I can tell from reading your issue is that your base_url parameter in your conf/config.php file is still pointing to exactly where it used to point to. That's not a bad thing and shouldn't need to be changed unless you want or need to have the second version of your url.

base url points to http://www.adamsweb.us/blog so that's what all your pages will end up being built with. AFTER the DNS nameserver propagation happens the same sequence of letters will point to the new physical location (your new server).

If you actually want or need your url to be http://adamswebus.temp.powweb.com/blog/index.php?blog=2 then you'll have to change the base_url param in conf/_config.php.

http://www.adamsweb.us/blog is what's on my old server. The domain just hasn't transferred yet.

What's here will be what's at http://www.adamsweb.us/blog

http://adamswebus.temp.powweb.com/blog/index.php?blog=2 is what will be on my new server.

I went ahead and by chainging the Base URL setting in /conf/th _config.php, I was able to log in to the version of b2evolution on my new server and it doesn't have any of my blog entries. Its completely blank.

Did you back up your database from the old server? If not I suggest you do so immediately, as without the database all your content is lost. After getting a backup you'll need to upload it to your new host, but one step at a time eh? The first thing is to make sure you have both your files AND your database from the old host.

EDIT: isn't there a wiki manual entry about this? Someone smart should link it even if/when the problem is resolved.
