 * Updated this morning to 2.9.1, and I’m getting the following error displayed 
   at the top of my page:
 * Warning: call_user_func_array() expects parameter 1 to be a valid callback, array
   must have exactly two members in /home/wwdeb981/public_html/energyattic/wp-includes/

 * The same problem as above. WordPress 4.5.3. + plugin 2.9.1.
    I have identical
   warning message.
 * Any quick help?

 * Yup – me too. Previous version rollback worked for me too.
