That’s because the URL the “View Profile” button on the forums is pointing to is no longer correct as the profile URLs have had “blizzard” added to them. Boubou reported this almost a week ago…
Hi,
Blizzard has “moved” the armouries / web profiles to diablo3.blizzard.com but hasn’t changed the View Profile button. As a result, the button still attempts to access armouries/web profiles on diablo3.com… fails… and gets re-routed to the Diablo III home page.
Hopefully, this is temporary… and will be fixed… soon™.
As an example, for my profile, the forums would direct you to…https://eu.diablo3.com/en-gb/profile/Meteorblade-2266/career
But the profile is now at…https://eu.diablo3.blizzard.com/en-gb/profile/Meteorblade-2266/career
