Hi,
I just installed the ad management Mod for my site http://pinoydownloads.net and it's not showing. Could you please help me?
You'll be needing to edit the theme you're using by editing the core templates via FTP. How do I use FTP? / What is FTP? (http://docs.simplemachines.org/index.php?topic=480)
The location of the files is %root%/%smf_root%/Themes/*name of theme*/
You can find manual modification instructions on that modification's thread and/or use the parser built in on the mod display.
