I too am now having redirect issues with the new update(s), first 3.1 and same with 3.1.0.1. When I login it gives the “Login Successful, redirecting” message, but the redirect never happens. I have a global redirect set up, and tried setting up role-based redirects (all to the same URL though) as well.
I reverted back to Version 3.0.4.1 and it works again.
