host move errors

I had to move my WP site from Dreamhost to hub. I tar’d the files on DH and downloaded them. I also exported the DB from DH. I then created a DB and domain on Hub, uploaded the files and extracted them to the new hub domain and then imported the .sql file to hub for the DB I had created. It all went smoothly.

On the new Hub site I created a portal html page as an entry point and from there will have users select the current blog I just moved OR click a second link to go to a NEW blog I am creating. In other words under my domain I created two sub folders and moved/installed WP into those two folders. That wa a visitor can visit the old blog or the new from the portal page.

However when I link to the OLD blog from the portal page using http://<mydomain>/folder1/ I get the basic OLD blog page to load with all the plugins, etc BUT the current blogs do not load and it shows NOT FOUND at the top of the page. What should the URL be to get the blog to show the posts?

The other problem is I have is that none of my user OR backend user accounts work. I get and ERROR 404 Not found when I try to log into my admin account from either the home page login plugin AND the wp-admin folder. None of my accounts work.

Since my URL did not change (just my nameservers changed ) did I miss doing something??

Thanks for any help
