I installed Social 2.5 MailChimp on wordpress 3.3.2. When I try to access ("sign in") with my Facebook or Twitter ID, it pops open the login for these sites, it allows me to log in, and then close that page. The blog page is not updated, and the keys "sign in with facebook" or "sign in with Twitter" are always there. Access has not been made.
The same two accounts are linked to my blog user account (admin) and when I log in as a user, I can send both as Facebook or Twitter without issues.
Please, could you help me?
The blog in question is http://www.valdesi.cs.it
