javascript — Понимание тегов кода Doubleclick

У нас возникают непонятные проблемы с Google Doubleclick

Баннеры постоянно показываются и исчезают.

Отладка покажет нам это:

gpt.js: 49 Не удалось выполнить «запись» в «Документ»: невозможно
записать в документ из асинхронно загруженного внешнего скрипта
если это явно не открыто.

Мы называем коды отдельно в php, потому что WordPress и LOLS

с помощью этой функции мы называем основной JS

function googletag(){
$googletag = "var googletag = googletag || {};
googletag.cmd = googletag.cmd || [];
(function(){
//console.log('Failed to display 3rd party ad, displaying google ad instead');
var gads = document.createElement('script');
gads.async = true;
gads.type = 'text/javascript';
var useSSL = 'https:' == document.location.protocol;
gads.src = (useSSL ? 'https:' : 'http:') + '//www.googletagservices.com/tag/js/gpt.js';
var node = document.getElementsByTagName('script')[0];
node.parentNode.insertBefore(gads, node);
})();
";

echo "\n<script>\n/* <![CDATA[ */$googletag\n/* ]]> */\n</script>\n";
}

а затем элементы DFP:

    <?php
function doubleclick(){
global $post;
$url = get_template_directory_uri();

$doubleclick = '';

if(is_category('11142')) {

$doubleclick .="<script src=\"$url/js/double/slot-allaccess.js\" type=\"text/javascript\" charset=\"utf-8\"></script>";

} else {

}

if(!empty($doubleclick)) {
$doubleclick = "\n<!-- Doubleclick Tag Script -->\n" . $doubleclick . "\n";
echo $doubleclick;
}

}

?>

И тогда мы размещаем один из баннеров:

function top_banner(){
if ( is_home() || is_front_page()) {

echo "<!-- home_960x90a -->";
echo "<div id=\"div-gpt-ad-1427326520458-38\" style=\"width:728px; height:90px;margin:0 auto;\">\n";
echo "<script>\n/* <![CDATA[ */\n";
echo "googletag.cmd.push(function() { googletag.display('div-gpt-ad-1427326520458-38'); });\n";
echo "/* ]]> */\n</script>\n";
echo "</div>\n";
}

Но ничего не работает, или хорошо работает иногда.
