I have recently re-installed the top-eleven application on my iPhone 4S(on the meantime i hadn't played this game for a while) and it seems impossible to log-in ( although from my fb account is it possible). It says "Your connection to Facebook has expired. Please log in again".
Type of phone: iPhone 4S
T11 Version: 2.35
FB Version: 20.1
iOS Version: 7.1.2

Can you please help me to solve this issue?

Thank you
