same problem here too. Also i was able to exclude all pages from search with custom code snippet but it doesnt’t work either now.

I can see the changed made to max choices, but in front end it doesn’t have affect.

add_filter("adverts_form_load", "limit_category_selection");
function limit_category_selection( $form ) {
    if($form["name"] != 'advert' || is_admin()) {
        return $form;
    }
    $count = count( $form["field"] );    
    for( $i = 0; $i < $count; $i++ ) {
        if($form["field"][$i]["name"] == "advert_category") {
            $form["field"][$i]["max_choices"] = 3;
        }
    }
    print_r($form["field"]);
    return $form;
}

url to my website

In my case, i have hid the subject box, and fill it with custom javascript. But if there is an easier way i would be happy to use as well. Just noting here to get notified of Greg’s answer.
