Hello, I have not updated my plugins for a while, and when I got to updating I think it was the Friends plugin I got this error message, and was not able to login again to try to fix it.

 Fatal error: Undefined class constant 'ON_USER_BLOCK' in /home/thompson/public_html/ow_plugins/friends/init.php on line 461

Can you please help me update these plugins.
