 * Hi, I am currently getting this error on the RSVPfy plugin for wordpress.
 * The WordPress version I am using is 4.7
 * Warning: call_user_func_array() expects parameter 1 to be a valid callback, no
   array or string given in /home/sollymay1/public_html/wp-includes/class-wp-hook.
   php on line 298
 * It started just after the update, so I know there might be a compatibility issue.
 * Best,
 * Salomon
