Can you try editing the /jfbcprofiles/communitybuilder/communitybuilder.php and jlinkedprofiles/... file. Around line 129 in the JFBConnect one, you'll see the following line:
$hideField = $cbField->type == 'primaryemailaddress' || $cbField->type == 'password' || $cbField->type == 'image' || $cbField->name == 'username';
Append "|| $cbField->type == 'cbprivacymainsettings'" to that, so it looks like:
$hideField = $cbField->type == 'primaryemailaddress' || $cbField->type == 'password' || $cbField->type == 'image' || $cbField->name == 'username' || $cbField->type == 'cbprivacymainsettings;
There's a similar line in the jlinkedprofiles plugin. That should hopefully skip our code that's trying to execute with that field. Not the best, most robust solution, but should get you going.
Let us know how that goes, or if you run into other problems after that one is fixed.
Thanks,
Alex
