How do I hide the “All fields marked with an * are required” message?

You can use the following CSS rule to hide the “All fields marked with an * are required” message:

CSS rules can be added in a few ways:

1. Added to your theme or child theme’s style.css;
2. Added via a plugin for adding custom CSS like: Simple Custom CSS; or
3. Added through the Jetpack custom CSS module.

Please note that this rule is CSS–that is, it is not JS or PHP, so please take care to avoid inadvertently adding it to a PHP or JS file, as this will result in errors. As always, never make changes to your site files that you cannot roll back.
