Warning: Missing argument 5 for fbc_get_avatar() in /home/you/public_html/wp-content/plugins/bp-fbconnect/wp-facebookconnect/fbconnect.php on line 528

In line 528 of fbconnect.php say:

function fbc_get_avatar( $avatar, $id_or_email, $dims, $size, $default) {

Remove the $dims variable

function fbc_get_avatar( $avatar, $id_or_email, $size, $default) {

and in line 534

return render_fb_profile_pic($fbuid, $size);

Worked also for me, it removed the error message
