Hi I know that I can update fields with the below condition
// CODE UPDATE
$option = get_option( 'settings' );
$option['new-text'] = $option['Text-old'];
update_option( 'settings', $option );
But now I need to know the way to get a field and clear that field just and not any block of options using wordpress delete_options
I need to clear old fields so that it does not hide space in the database.
Thanks for the great work with Meta Box
