Why aren't Google Adsense automated ads showing up?

Question

Google Adsense

On the pages of the forum, as well as on all other pages of the site, the Google automated ads code is installed.
Such:

<script async src="//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script>
<script>
     (adsbygoogle = window.adsbygoogle || []).push({
          google_ad_client: "ca-pub",
          enable_page_level_ads: true
     });
</script>

All pages show ads, but the forum does not. Why is that?
The code has been standing for more than six months.

Answer 1

, apparently, the forum cannot be scanned
