You edited the path out of the error message, but did it include the health_blog part, as well as forum? So it looked like /something/health_blog/forums/forum.php ?

/usr/local/www/vhosts/healthstatus.com/htdocs/health_blog/forums/forum.php

Maybe it’s one directory off or something?

One thing weird about the link to a forum: the URL looks like:

http://www.healthstatus.com/health_blog/forums/forum/healthstatus-forums

when they should look like

http://www.healthstatus.com/health_blog/forums/healthstatus-forums

(I think – is there an extra “forum” in there?)

Can you turn off the mod_rewrite in .htaccess and try it without permalinks? If it works, maybe the rewrite rules are borked.

Try this: $bb->mod_rewrite = false;
