how do i ad adsense to my phpBB forum. and i know that you can add it to every page because i have seen other phpBB forums with it. my forum is in my signature link if you have never seen a phpBB forum before...
ACP -> Styles -> Templates -> Edit -> Choose overall_header.html from the list. Search: <!-- IF S_DISPLAY_SEARCH and not S_IN_SEARCH --> Code (markup): Add your AdSense code just before: <div id="search-box"> Code (markup): Tell me if it worked.
checkout the phpbb forum help site, im pretty sure they will have mods for the forum that will be easy ad management.
