Hi Carsten,
If you ceate a js file, you will need the code to load it too.

Since it is just 2 lines of code, My suggestion will be to put it in one of the js file provided by theme. Look for a file named buddypress.js and you can put the code inside the dom ready section there. If you are using a custom theme, you may ask there(or check their documents) to see if there is any custom js file supported.

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.
