Re: group avatar problem
Go to Settings -> Miscellaneous Settings

Set “Store uploads in this folder” to “wp-content/uploads”.

Set “Full URL path to files” to the REAL FULL PATH of your uploads.

Then change bp-core-avatars.php line 389:
Replace
:
if ( !$path = get_option( ‘upload_path’ ) )

$path = WP_CONTENT_DIR . ‘/uploads’;

With:

if ( !$path = get_option( ‘upload_path’ ) )

$path = WP_CONTENT_DIR . ‘/uploads’;
else
$path = ABSPATH . $path;
It fixes the problem.
Since this is a modification in one core file, you need to do that everytime you upgrade BP. Don’t foget!
Unless it gets fixed in the future.
