google-site-verification /google adsense verification

Hello,
I need some help:
I don't succeed in verifying the google-site and google adsense.
I'm using a plugin for facebook/youtube/google+ - this works.
But the identification for google doesn't work.
Google asked me to put the following into the head/html:
<meta name="google-site-verification" content=".....number....." />
and
<script async src="//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script>
<script>
(adsbygoogle = window.adsbygoogle || []).push({
google_ad_client: "...code-number.....",
enable_page_level_ads: true
});
</script>

I wasn't sure, so I had a look in the generatepress support.
In GP-Hooks I added:

<meta name="google-site-verification" content="....number..... />
add_shortcode( 'adsense' , 'my_adsense_shortcode' );
function my_adsense_shortcode()
{
ob_start();
?>
<script async src="//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script>
<!-- Ad code -->
<ins class="adsbygoogle"
style="display:block"
data-ad-client: "....code-number...."
data-ad-slot:"...number..."
data-ad-format="auto"></ins>
<script>
(adsbygoogle = window.adsbygoogle || []).push({});
</script>
<?php
return ob_get_clean();
}

I activated php and saved the Hooks.
Then I had a look in the html-background of the website and couldn't find anything.
And I assume google doesn't find anything either.

What's wrong?
Thank you for helping!
