BuddyPress.org

I just emailed them. I did a complete re-install of WP so I could get a fresh start to enable the newtowrk. I got the same open_basedir restriction when trying to upload avatars, but this time I at least got more useable error info to email the host with. This is what it said this time:
Warning: is_dir() [function.is-dir]: open_basedir restriction in effect. File(/) is not within the allowed path(s): (/home/wwwnatf:/usr/lib/php:/usr/local/lib/php:/tmp) in /home/wwwnatf/public_html/wp-includes/functions.php on line 2037

Upload Failed! Error was: Unable to create directory /group-avatars/1. Is its parent directory writable by the server?

I wonder if it’s just a CHMOD issue or a CHOWN one?

EDIT
Ok Tech mailed me back with this:
I have disabled open base restriction for, natfriends.com. Please check it now and let us know if you need any further assistance.

But I still can’t upload. When I do I get this error message:
Upload Failed! Error was: Unable to create directory /group-avatars/1. Is its parent directory writable by the server?

Where is this directory “/group-avatars/1” what folder does it live in? Maybe permissions need to be 755?

Thanks!
