You should be able to over-load the Activity-Loop so that it does not show new posts:

Activity Loop

How To Customize The BuddyPress Activity Loop

I’d override the template by copying the existing template at wp-content/plugins/buddypress/src/bp-templates/bp-legacy/buddypress/members/single/member-header.php

and adding it to my theme at: buddypress/members/single/member-header.php

Add a permissions check around the block you’re wanting to restrict access to (something like this):

<?php if ( bp_current_user_can( 'bp_moderate' ) ): ?>
	<span class="activity" data-livestamp="<?php bp_core_iso8601_date( bp_get_user_last_activity( bp_displayed_user_id() ) ); ?>"><?php bp_last_activity( bp_displayed_user_id() ); ?></span>
<?php endif; ?>

@stevie79 You can easily use custom css

#buddypress span.activity {
    display: none!important;
}

@panthony54 You can install email template again from Tools >> BuddyPress.

@tom-corvus You can check codes at
https://plugins.svn.wordpress.org/bp-default-data/tags/1.2.0/process.php with function name bpdd_import_users_profile()
BP Default data plugin have created some fields and field group for BuddyPress.

@grounder Try to update BuddyPress at your site and if you are already using the updated version, you can go to Tools >> BuddyPress to repair tables.
If your database is huge then I will suggest repairing all options one by one.

@digitalyak instead of modifying plugin file directly, you can override these template files inside child theme at the following path and then add your changes, it will preserve your edit even after plugin updates

child-theme-folder/buddypress/members/single/messages/

BuddyPress is alive! 🙂

You can use the BuddyPress REST API for that: https://github.com/buddypress/BP-REST/

It is still a work in progress. But usable.

You can use one of the BuddyPress privacy plugins to set aspects of your site as private and visible only to logged in users. For example it’s a feature of BuddyPress Registration Options or BuddyPress Simple Privacy, or BuddyPress Members Only.

BuddyPress has not been abandoned. It’s alive and kicking.
