@ronia, yes, the latest version is 1.2.5, as far as I know, and 1.3 will officially support WP 3.0. So if you upgrade you have nothing to worry about. My problem is that I want to stay on BP 1.1.3, trying to get that to work on 3.0.

The key to solve that is here. Putting this in bp-custom.php worked for me:

define( ‘BP_AVATAR_URL’, ‘http://’ . $_SERVER . ‘/wp-content/blogs.dir/1/files’ );
define( ‘BP_AVATAR_UPLOAD_PATH’, $_SERVER . ‘/wp-content/blogs.dir/1/files’);

Still have to copy more avatar code from 1.2.5 to get everything to work in 1.1.3…
