 * Everything seems to be working, but I am getting this error on certain admin 
   pages:
    Missing argument 2 for WPCACore::add_group_meta_box() in content-aware-
   sidebars /lib/wp-content-aware-engine/core.php
 * Can you shed any light on this?

 * Thank you for reporting this, I can see there is a minor bug causing the error.
   Can I ask you what version of PHP you are using?
 * The error should not cause any harm, but if you want to remove the message right
   now, go to the mentioned file, line 99 and replace:
 *     ```
       add_action('add_meta_boxes',array(__CLASS__,'add_group_meta_box'),10,3);
       ```
   
 * with:
 *     ```
       add_action('add_meta_boxes',array(__CLASS__,'add_group_meta_box'),10,2);
       ```
