I uploaded ad management to my site and it only displays on my default theme. Can someone tell me how to upload it so it works on my sg black theme? thanks
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 file 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.
