After installation of the plugin on multi-site WP the network console went down.
It shoes error message
Fatal error: Call to undefined function wp_get_current_user() in /home/sbtv/public_html/wp-includes/capabilities.php on line 1187
and that's it. I can do nothing. I'm not sure if i physically remove this plugin will it resolve the problem. By the way site consoles work fine. Only network consoled stopped working.
