Root Cause: Some hidden config fields do not have array key 'default' The error occurs at line 56 $field_array['value'] = $field_array['default'];

Solution: Replace line 56 with:

                //$field_array['value'] = $field_array['default'];
                if (array_key_exists('default', $field_array)) {
                    $field_array['value'] = $field_array['default'];
                } else {
                    $field_array['value'] = '';
                }
