Need more information. What version did you have before, what version did you upgrade to, how did you do the upgrade, were there any errors during the upgrade?

I went to that link and a site came up, what is supposed to come up?

I upgraded with the new version 8.2.1..
The page that should appear is my home page.
But I made a mistake, I added a simplified Url and since I do not have my homepage.
I removed it but no change ...
