Redirect error

Your best bet is to disable our Login Redirect module, then see what the redirect behaviours are. That may give you an indication of what’s causing the conflicting redirect (though normally ours would just be overridden, so I’m not sure that our Toolkit is causing the loop). You should disable our module regardless; you can’t have users dealing with those redirect loops. Maybe try testing behaviours on a Staging site using users with different roles.
