Post Formats is a WordPress theme feature. See https://codex.wordpress.org/Post_Formats. Try asking your question at https://wordpress.org/support/

Check with the users that the email isn’t in the junk folder. This often happens so I usually recommend checking that first.

I tried BP Reactions after activating it, it does not show up

You could try opening an issue on the plugin’s forum: https://wordpress.org/support/plugin/bp-reactions

Add 301 redirect code in your page to redirect login page.

I use buddypress plugins to optimize it.

You can certainly use BuddyPress WP CLI for that: https://github.com/buddypress/wp-cli-buddypress

It has a wp bp group member command.

Something like wp bp group member --group-id={GROUP_ID} --user-id={MEMBER_ID}

@graeme_bryson and for anyone else who wants to know, this code should work!
function my_activity_posted_by_action( $action, $activity ) {
$action = sprintf( __( '%s', 'buddypress' ), bp_core_get_userlink( $activity->user_id ) );
return $action;
}
add_filter( 'bp_activity_new_update_action', 'my_activity_posted_by_action', 1, 2…

This should do the trick:

function bgmc_nosubs_redirect() {

}
add_filter( 'template_redirect', 'bgmc_nosubs_redirect' );


Note – untested, but theory is sound 🙂
