Hi Irina,
on 4.9.8 it is part of the core.

My guess is it is either Youzer or the theme. Try disabling Youzer and then checking it.

If that does not work and if the site is still in development, please try switching theme and checking again.

Let me know what you find there.

Sure, Here is the functiona updated again.

function mktbn_user_register( $user_id )
{
	if ( function_exists( 'mikakoo_log' ) ) {
		mikakoo_log( 'user_register: ' . $user_id );
	}

	if ( ! empty( $_POST['MemberType'] ) && function_exists( 'bp_set_member_type' ) ) {
		bp_set_member_type( $user_id, $_POST['MemberType'] );
	}

	$user = get_user_by( 'id', $user_id );

	// if member type submitted and valid user and the person adding user is super admin
    // then set role too.
	if ( $user && ! empty( $_POST['MemberType'] ) && is_super_admin() ) {
	    $user->set_role($_POST['MemberType'] );
	}

}

Hi Jeff,
Please share the complete code for function mktbn_user_register()

Most probably there is some syntaxt error causing it.

Hi Jeff,
We have a filter to allow any user to act as admin for deactivation.

Here is an example where I am checking if the current user is editor and if it is true, we allow to see the button and do it for other users.

/**
 * @param $allow
 *
 * @return bool
 */
function buddydev_custom_deactivator_permission( $allow ) {

	// let us allow editors.
	if ( ! $allow ) {
		$allow = current_user_can( 'delete_others_posts' );
	}

	return $allow;
}

add_filter( 'bp_account_deactivator_user_can_change_account_status', 'buddydev_custom_deactivator_permission' );

If you have a custom role, You may be using some custom capability. You can swap the capability with your own.

Please let me know if it works.

Regards
Brajesh
