Google adsense in phpBB 3 (at the bottom or at the top)

To add something at the bottom of your phpBB 3.x forum, edit the “overall_footer.html” file for the template(s) available on your phpBB: add whatever you want just before:

</body>
</html>

To add something at the top, edit “overall_header.htm” near:

<h1>{SITENAME}</h1>
