thanks, I used a trick in php in fonctions.php in the admin init hook

function prevent_admin_access() {

if (strpos(strtolower($_SERVER['REQUEST_URI']), '/wp-admin') !== false && !current_user_can('administrator') &&  !defined( 'DOING_AJAX' )  ) {
	wp_redirect(get_option('siteurl'));
	}
}

add_action('admin_init', 'prevent_admin_access', 0);

I had to modify your code to show them up in post excerps hope you don’t mind it.

you are right, the issue come from my redirection, that’s why I have a 302 error, the ajax page is non reachable. As I did my tests with the admin credentials I didn’t notice that.

Thanks a lot, I could have spent a week on that,
