How to null Gravity Forms – The most complete WordPress form plugin

You don’t need to input license key to use this plugin. Just click the button in the license screen and go on. However, at some point there will be a nag in the admin area asking for license. Put below code in your functions.php file or just use Code Snippets plugin:

function remove_gravity_forms_nag() {
update_option( 'rg_gforms_message', '' );
remove_action( 'after_plugin_row_gravityforms/gravityforms.php', array( 'GFForms', 'plugin_row' ) );
}
add_action( 'admin_init', 'remove_gravity_forms_nag' );

Now you’re good to go.
