Integration of plugin for Buddypress with Affiliates not working

Hi
I’ve finished integrating the Affiliate Enterprise system with my Woocommerce site, and linked it with Buddypress and also bought your Buddypress/Affiliate integration plugin, so that when someone joins they are mirrored in both affiliates and Buddypress.

However, it’s not working.
If you go here and register just as an affiliate, it is not recorded in the system, and all that happens is an error:
https://www.ajnagold.com/affiliate-area/

Warning: Cannot modify header information – headers already sent by (output started at /home/goldli8/public_html/ajnagold.com/wp-content/themes/eduma/header.php:10) in /home/goldli8/public_html/ajnagold.com/wp-includes/pluggable.php on line 1174

However, perhaps that register as an affiliate form should not be used? Does the mirroring of affiliates into Buddypress members and Buddypress members automatically into affiliates work both ways? Perhaps a user should only register as a Buddypress member?

MAJOR PROBLEM: If you go here and register through the full Buddypress members system it does work… but it doesn’t save any of the affiliate specific questions being recorded in the database.

So after you’ve filled out all the (affiliate) fields when you register as a Buddypress member, none of those affiliate fields are saved, and you have to try and enter them again. And it won’t save them. You can see when you look at your own affiliates area:

I’m sending you an email with my login details for my site. I’d really appreciate if you can please help me fix this problem, it is very urgent.
Thanks
