BuddyPress.org

OVERVIEW OF SETUP:
I have Extended Profiles enabled.
In Users/Profile Fields, I have a “test” field in the primary tab.
I have a second Field Group with another “test” field.
I also have s2Member Pro installed with profile fields setup there.

REGISTER PAGE NOT WORKING CORRECTLY:
It displays the first Field Group with the first test field.
It displays the s2Member profile fields.
NONE of the BuddyPress second Field Group is displayed.
Instead, it displays an error message:
“Profile Details
Warning: Creating default object from empty value in /home/content/p3pnexwpnas09_data01/28/2853428/html/wp-content/plugins/buddypress/bp-xprofile/classes/class-bp-xprofile-group.php on line 649”

Line 649 is:
$fields[ $key ]->visibility_level = $field_visibility;

AND !! Hitting the submit button (Complete Signup Now) is not completing the registration.

S2Member is trying to help, but they now state this is a BuddyPress issue. I also note that when I make Admin edits to User Profiles sometimes new fields appear from seemingly nowhere. For example, I have had approximately 10 fields requiring First Name appear in the Primary tab even before s2Member was installed.

ANY HELP? I am not a programmer and this is beyond my expertise.
