BuddyPress.org

I tried the code posted here ( https://buddypress.org/support/topic/display-username-in-members-directory/#post-89522 ) into functions.php and got the whitescreen of critical error.
– That code was supposed to display username and full name in the directory I think.

been looking into copying template page ( \buddypress\bp-templates\bp-legacy\buddypress\members\members-loop.php )
into new /buddypress/ folder and adding some code there(?)

Do I need to add somethng like:
bp_user_fullname()
bp_displayed_user_fullname()

Also looking at some things for x-profile tags?
Not sure best way to go / get there from here..

I did try adding a file to:
/wp-content/themes/twenty-four-cslite/buddypress/bp-templates/bp-legacy/buddypress/members/members-loop.php

and putting part like this:

				<div class="item-title">
					<a href="<?php bp_member_permalink(); ?>"><?php bp_member_name(); ?></a>
					<br>
					<?php bp_displayed_user_fullname(); ?>
					<?php if ( bp_get_member_latest_update() ) : ?>

						<span class="update"> <?php bp_member_latest_update(); ?></span>

					<?php endif; ?>

but it did not seem to do anything… Feel like I am close but missing things – I did a lot of searching, but missing something obviously.
