Hi ivanco, thanks for your answer. I know it but if I put the same code:
<script>
(adsbygoogle = window.adsbygoogle || []).push({
google_ad_client: "ca-pub-xxxxxxxxxxxx",
enable_page_level_ads: true
});
</script>
the console show me this error message(look the image).I tryed with showads.js (another js of google adsense) and it doen't work.
and I haven't put the code for showing the banner in that position(on top of categories, as you see in the first image).
Thanks
