I can only access Sitewide Forums I create with WP default permalinks but BuddyPress says it won’t work unless I change from default. When I change from default I get a error about too many redirects or a redirect loop that won’t complete when I try to view the forum.
I have WP 3.2.1 with BP 1.5 set up as a subdirectory install in the root of a GoDaddy Linux hosting package. Group Forums turned off, Sitewide Forms activated which installed bbPress 2.0 plugin. My .htaccess file looks like:

# BEGIN WordPress

RewriteEngine On
RewriteBase /
RewriteRule ^index.php$ – [L]

# uploaded files
RewriteRule ^([_0-9a-zA-Z-]+/)?files/(.+) wp-includes/ms-files.php?file=$2 [L]

# add a trailing slash to /wp-admin
RewriteRule ^([_0-9a-zA-Z-]+/)?wp-admin$ $1wp-admin/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ – [L]
RewriteRule ^[_0-9a-zA-Z-]+/(wp-(content|admin|includes).*) $1 [L]
RewriteRule ^[_0-9a-zA-Z-]+/(.*.php)$ $1 [L]
RewriteRule . index.php [L]

# END WordPress

There is no blank space at the top.
Any help would be appreciated.

Problem solved.
In response to an error message about possible conflicts, had changed the Form Base slug under Archive Slugs in Settings->Forums rather than the Forum Slug under Single Slugs.
Now I’ve changed the Archive Slug back to “forum” and changed the Single Slug to “sitewide-forums” and everything works great.
Hope this helps someone else.
