checkbox default 'on' not working

[alekseyn1]

Here is a working solution.
Replace the entire case: entry with this

			case 'checkbox':
				$checked = '';
				
			       global $wpdb;
			       $empty_option = false;
			       $row = $wpdb->get_row($wpdb->prepare("SELECT option_value FROM $wpdb->options WHERE option_name = %s LIMIT 1", $option_name));
			       if (is_object($row)) {
			           $empty_option = true;
			       }
				
				if( ($option) || ( $empty_option == false && $field['default'] ) ){
					$checked = 'checked="checked"';
				}
				$html .= '<input id="' . esc_attr( $field['id'] ) . '" type="' . $field['type'] . '" name="' . esc_attr( $option_name ) . '" ' . $checked . '/>' . "\n";
			break;

Hey @alekseyn1 thanks for this.

Are you able to open a pull request with these changes. I can't guarantee I will be able to merge it very soon, but if it's open I can at least try and prioritise it.
