Redirections don’t work if URI contains “p” parameter

Hello,

Thank you for contacting Rank Math for help with redirecting your custom post type.

The ‘p’ parameter is triggered by WordPress before Rank Math redirects. You could use a WordPress ‘template_redirect’ filter instead. Please try this code snippet:

add_action( 'template_redirect', 'redirect_jbjob');

function redirect_jbjob() {
	if (isset($_GET['post_type'])) {
		$queried_post_type = $_GET['post_type'];
	}else{
		$queried_post_type = "";
	}
	if ( 'jb-job' ==  $queried_post_type ) {
    	wp_redirect(home_url(), 301);
	}
}

You can refer to this guide for how to add code snippets: https://rankmath.com/kb/wordpress-hooks-actions-filters/

Hope that helps. Please let us know if you have questions.
