It should be an easy thing to hide the “”(*)" indicates required fields" notice. Instead, you’re asking non-coders to edit their functions.php file, which can produce a fatal error if you don’t know what you’re doing, or make a mistake. I can’t believe that this is the only way to get rid of it. Why is this? Why not take 15 minutes and add a checkbox to form setting that would hide/show the notification?
