[xwiki-users] SocialLogin error

4 Apr 2012


      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
