You need to adjust the proper template.
But don’t edit the templates in the plugin or your changes will be wiped out when you update BP.
Instead, overload the template:

Theme Compatibility & Template Files

Re RED: you didn’t say which template pack you are using. I will assume it is Nouveau.
Over load this template:
wp-content\plugins\buddypress\bp-templates\bp-nouveau\buddypress\members\single\member-header.php
Then open the overload template and find this code near the top:

<?php if ( bp_is_active( 'activity' ) && bp_activity_do_mentions() ) : ?>
	<h2 class="user-nicename">@<?php bp_displayed_user_mentionname(); ?></h2>
<?php endif; ?>

And simply remove the conditional, so it will look like this:

<h2 class="user-nicename">@<?php bp_displayed_user_mentionname(); ?></h2>

Your other questions are more complex, but will require the same approach:

– identify the template(s) you need to change
– overload them
– make your changes

subscriptions-tab.php is a custom file in your child theme, correct?

The obvious guess is that there is a problem with the code in that file.
Unless you share that code, it is difficult to know what the problem is.
Please do not post the code here.
Use a site like pastbin to share your code and then post the url here.

I’d suggest you to deactivate all plugins but BuddyPress and switch to a Twenty* theme. What you describe can be caused by another plugin or your current theme. Sometimes Cache plugins are also wrongly minifying JavaScript templates which can prevent the JavaScript to do its job.

That depends on what theme you’re using. If you find out what template or function is producing the author page, you can add a link the user’s profile page using the function bp_core_get_user_domain( $user_id ). You’ll have to pass in the correct user ID, which should be used in the author page, too.

Your addition might look like
<a href="<?php echo bp_core_get_user_domain( $user_id ); ?>">Visit User Profile</a>

Hi @visitatore-

The username is used extensively through BuddyPress, so I don’t know how it can be kept a secret. (For instance, it’s used for the user’s profile page url at /members/{username}.)

I don’t think you can hide the username entirely, since the BP messaging and mention system is built on the username, but you could probably change out some references to the username in the messaging templates by overriding message templates as described here: https://codex.buddypress.org/themes/theme-compatibility-1-7/a-quick-look-at-1-7-theme-compatibility/

That’s pretty old code you’ve found. We have a new API for that:

Navigation API

The example “Changing the name of the Unread subnav item of the user’s Notifications nav menu” is pretty close to what you’re looking for. If you want to add the displayed user’s display name, this is close:

function bpcodex_change_activity_nav_name() {

var_dump( buddypress()->members->nav );
    buddypress()->members->nav->edit_nav( array(
        'name' => bp_get_displayed_user_fullname() . "'s Feed",
    ), 'activity' );
}
add_action( 'bp_setup_nav', 'bpcodex_change_activity_nav_name', 100 );

You’ll need to add that code to your bp-custom.php file or similar. https://codex.buddypress.org/themes/bp-custom-php/

Hi @pixieblitz The most simple way is too put all your fields into the default profile tab from the fields WP Admin.

You can probably list all fields on the edit screen on the front-end overriding the template from your child theme. You should have a look at https://codex.buddypress.org/themes/theme-compatibility-1-7/a-quick-look-at-1-7-theme-compatibility/

That really depends on your theme. You can use your browser’s inspector to see what CSS rules are causing the layout, then override them by adding custom rules to your site via the customizer or by using a child theme.
