Re: Any way to change forum base URL?
Because you have WP setup in site.com/blog/, this isn’t really possible.
It may be possible to use some rewrite rules in .htaccess, but I’m not sure.
Keep in mind that if you install a standalone version of bbPress, you’ll essentially have two forums unless you:
A) Disable the forum component in BP, or
hide the references to the site.com/blog/forum link.
