Hi Mike,
Thank you for the question.
It is a known Bug in bbPress extension for BuddyPress(comes with bbPress plugin).

Please add this to your bp-custom.php

// Fix BbPress 2.6 bug not allowing handling of subscription actions from profile.
add_action( 'bp_actions', function () {

	if ( empty( $_GET['action'] ) || ! is_string( $_GET['action'] ) || ! function_exists( 'bbp_subscriptions_handler' ) ) {
		return;
	}

	// Sanitize the GET action
	$action = sanitize_key( $_GET['action'] );

	// Bail if action was totally invalid
	if ( empty( $action ) ) {
		return;
	}

	bbp_subscriptions_handler( $action );
}, 1 );

Let me know if that works for you or not. i haven’t tested this fix in recent version.

Hi Cristi,
I am sorry, we made a mistake a used another hook name in release.

Please keep the above line as we will be renaming back to that and you can use this instead for the time being.

add_filter( 'bblpro_disable_media_listing', '__return_true' );

Hi Didier,
Thank you for the patience and checking back.

We are almost done with it. At the moment, we are working on Group admin settings(having control over types, who can post and other aspects). I am expecting a beta by the end of this week and a final release by the month end.
