Im getting a warning on my member pages

Warning: call_user_func_array() expects parameter 1 to be a valid callback, function ‘wds_bp_registration_options_bp_before_member_header’ not found or invalid function name in /home/eldraw/sparezucchini.org/wp-includes/plugin.php on line 406

This warning message shows up above the profile photo and other information. Can anyone tell how to fix this?

Thanks.
