How to change the registration page URL in the login section

Add this code to your child theme’s  functions.php file or via a plugin that allows custom functions to be added, such as the Code snippets plugin. Avoid adding custom code directly to your parent theme’s functions.php file, as this will be wiped entirely when you update the theme.

add_filter( 'register_url', 'custom_register_url' );
function custom_register_url( $register_url ){
	$register_url = "YOUR_PAGE_URL";
	return $register_url;
}
