agneesze, were you registered on this site before the problem started? I wasnât and also couldnât log in here with my regular Twitter account.
Perhaps try creating a âthrowawayâ Twitter account registered to a different email address like I did. See if it can access Settings->Widgets or not; my throwaway could when my regular couldnât. My regular account started working two days later, which I assumed was the work of andypiper, but until he responds here we shouldnât assume anything, especially because the problem isnât fixed for everyone.
