If I wanted to move my forum to a subdomain, what paths and where would I update?
So only that one path?Update this setting:
Admin CP -> Home -> Options -> Basic Board Information -> Board URL
That should do it.
Then be sure to copy all of the forum files to the new location. Be mindful that attachments and avatars are stored in the data directory.
You seem to not understand. I already have my forum on the server, just want to change the URL a bit. Physically the files aren't even moving folders, I am just pointing a subdomain to that folder that they are in now. The server works already, the dns works, the forum works. Just moving to a subdomain...?????? Have you configured your Server and DNS first ?
