[xwiki-users] SocialLogin error

Wed, 04 Apr 2012 04:13:12 -0700 

Dear,
I installed the Social Login extension from the control panel in the last xwiki-xem manager with two sub-wiki, I can't get the login working. I attached the full error, it's a null pointer exceptions, but I can't find a reference to the exact macro line. 

Thank you,
Gianluca
