 * The plugin (Premium version) produces a warning after updating to the latest 
   version: `Undefined array key "follow_filtering"`
 * stack trace inside the plugin is:
    wpdatatables/source/class.wpdatachart.php:
   3535 wpdatatables/controllers/wdt_functions.php:631
 * saving the settings of the affected chart does solve it, but it shouldn’t start
   producing warnings just by updating.
