I know this is probably an easy answer, but I couldn’t find a thread that explained it fully. I’m trying to install to a subdomain in my WordPress site. I add the folder to my “WP-Content>Plugin” folder, then activate it. However I don’t know how to make it point to my subdomain. I created the subdomain yesterday, so it should be active, I just don’t know if there’s a config file, or where in the WordPress settings I need to make the change. I’m installing bbpress ver 2.0, my main site is http://letterstoreason.com and the subdomain is http://forum.letterstoreason.com if that helps. I know it’s gotta be staring me in the face, I’ve just been Googling and can’t find the damn answer :S any help would be GREATLY appreciated.
