Thanks for the link. I followed another blog post that was very similar but I had some problems. It seem to upgrade fine and I followed all the steps, included copying over the connection strings and the validation keys. Now when I try and login it just takes me back to my Home page and acts like I never even logged in. No control pannel or anything. The register/login buttons at the top still appear. I tried creating a new account under a random name and it let me register but still no log in. It knows the password though because if I misstype it there's an error and it wont let me finish the log in process. So I type it in correctly and it takes me back to the Home page without being loggen in. Any clues? I'm using Goddady and upgraded from a working 4.8.0 to 4.8.2. Thanks for any help.

Maybe the core team can officially comment..  is that the only difference between install and upgrade?
