hi @amanor, @addd4567

you have to create a child theme to di this correctly.

Then add /bp-default/header.php to /your-child/header.php
Line 42 is a php content who begins by wp_nav…..

At the begin of the line, just after the php opening tag, add
if (  is_user_logged_in()  ):
wp_nav_content…. bla bla…

and at the end of the line, just before the php closing tag, add endif;

The nav bar is now hidden for any not logged in visitor

Thank you Chouf. I am using wmpu’s Holder BP theme, with the block style selected. In my header.php file, I only find wp_title and wp_head.
