 * Hi there. I installed pinterest widgets on my multisite a while ago and everything
   has been fine up until the point at which I tried to create a new subsite. I 
   received the error:
    Warning: call_user_func_array() expects parameter 1 to be
   a valid callback, class ‘Pinterest_Widgets’ does not have a method ‘activate_new_site’
   in /srv/users/app115/apps/bloggfu/public/wp-includes/plugin.php on line 503
 * Warning: Cannot modify header information – headers already sent by (output started
   at /srv/users/app115/apps/bloggfu/public/wp-includes/plugin.php:503) in /srv/
   users/app115/apps/bloggfu/public/wp-includes/pluggable.php on line 1207
    Any 
   suggestions?
